This string query operation was supposed to be replaced by the
generic get_sset_count() starting in 2007.  Convert tehuti's
implementation.

Also remove the dummy self-test name which was not used since tehuti
does not advertise any self-tests.

Subject: net: Convert ethtool {get_stats, self_test}_count() ops to
 get_sset_count()

These string query operations were supposed to be replaced by the
generic get_sset_count() starting in 2007.  Convert the remaining
implementations.

Also remove calls to these operations to initialise drvinfo->n_stats.
The ethtool core code already does that.

Subject: usbnet: Set device type for wlan and wwan devices

For usbnet devices with FLAG_WLAN and FLAG_WWAN set the proper device
type so that uevent contains the correct value. This then allows an easy
identification of the actual underlying technology of the Ethernet device.

Subject: igb: remove unused temp variable from stats clearing path

There is a temp variable in the stats clearing path that isn't needed since
the results from the stats read can be immediately discared.  Since it
isn't needed we might as well just drop it from the function call.

Subject: igb: update the approach taken to acquiring and releasing the phy
 lock

The current approach is just using a ?: type mechanism to set the phy
locking bit.  This if fine for now but limits us to only 2.  Switch to a
nested if statement for future compatiblity with more than 2 phys.

Subject: igb: add locking to reads of the i2c interface

The current implementation of sgmii support isn't correctly locking the
interfaces for reads/writes.  This change pulls the read/write
functionality out of 82575.c and moves it to phy.c.  In addition it
replaces the implementation in 82575.c with one that uses locking around
the relocated i2c interface calls.

Subject: igb: make use of the uta to allow for promiscous mode filter

In order to support functions such as vlan tag stripping when SR-IOV is
enabled any given packet must match at least one filter.  However in the
case of promiscous mode being enabled on the PF the traffic routed to it
may not match any filters and is just sent to the PF by default.  In order
to make certain that this traffic is processed we can set all bits in the
UTA registers to create a pseudo promiscous mode filter that accepts all
packets.

Subject: igb: add function to handle mailbox lock

Both the read and write mailbox functions need to acquire the mailbox lock.
Since that is the case we might as well combine both of the procedures into
one function so it is easier to maintain.

Subject: igb: change how we handle alternate mac addresses

This patch allows us to treat the alternate mac address as though it is the
physical address on the adapter.  This is accomplished by letting the
alt_mac_address function to only fail on an NVM error.  If no errors occur
and the alternate mac address is not present then RAR0 is read as the
default mac address.

Subject: igb: add code to retry a phy read in the event of failure on link
 check

This patch adds a retry to phy reads in the event of failure.  The original
code broke out of the loop on failure and this is a mistake as we should be
trying to do the read twice.

Subject: igb: add additional error handling to the phy code

This update adds additional exception handling to the phy code to handle
situations where it may be called incorrectly.  In addition it adds some
bounds checking to the cable length checks to prevent an array overrun in
the event that the hardware returned a different value than expected.

There are some switches that will do write combining when they see two
sequential regions written. In order to avoid any possible write combining
issues it is necessary to add a flush after writing each piece of a rar

Subject: vxge: Modify __vxge_hw_device_is_privilaged() to not assume
 function-0 as the privileged function: Resubmit#1

- vxge driver was assuming function-0 is always the privilaged function. Now that
  restriction has been removed any function can act as a privilaged function.

- This patch modifies the __vxge_hw_device_is_privilaged routine to not assume
  function-0 as the privileged function.

- Recreated the patch by incorporating review comments from Dave Miller to
  remove double slash in path names.

Subject: vxge: Update driver_config->vpath_per_dev for each function in probe.

- Update driver_config->vpath_per_dev for each function in probe.

- vpath_per_device specifies number of vpaths supported for each function/device. The
  current code was updating vpath_per_device only for physical device, however this has
  to be updated for each function also in case of a MF(Multi function) device.

Subject: vxge: Removed accessing non-supported registers.

- Removed accessing GENDMA_INT register
 - This allowed the firmware to perform a generic DMA write to host memory.
   This feature is not supported by the ASIC, this patch removes access to
   GENDMA_INT register.

Subject: vxge: Check if FCS stripping is disabled by the firmware.

- Added a function to check if FCS stripping is disabled by the firmware, if
  it is not disabled fail driver load.

- By default FCS stripping is disabled by the firmware. With this assumption
  driver decrements the indicated packet length by 4 bytes(FCS length).

- This patch ensures that FCS stripping is disabled during driver load time.

From: Tilman Schmidt <tilman@imap.cc>
Date: Tue, 6 Oct 2009 12:19:07 +0000
Subject: gigaset: prepare for CAPI implementation

Reorganize the code of the Gigaset driver, moving all isdn4linux
dependencies to the source file i4l.c so that it can be replaced
by a file capi.c interfacing to Kernel CAPI instead.

Impact: refactoring, no functional change

Subject: gigaset: allow building without I4L

Add a dummy LL interface to the Gigaset driver so that it can be
built and, in a limited way, used without the ISDN4Linux subsystem.

From a549952ad323d68daf5b50bf716db895479af84c Mon Sep 17 00:00:00 2001
From: Jiri Pirko <jpirko@redhat.com>

Subject: bonding: introduce primary_reselect option

In some cases there is not desirable to switch back to primary interface when
it's link recovers and rather stay with currently active one. We need to avoid
packetloss as much as we can in some cases. This is solved by introducing
primary_reselect option. Note that enslaved primary slave is set as current
active no matter what.

Patch modified by Jay Vosburgh as follows: fixed bug in action
after change of option setting via sysfs, revised the documentation
update, and bumped the bonding version number.

Subject: net/ppp: fix comments - ppp_{sync,asynctty}_receive() may sleep

The receive_buf methods of the N_PPP and N_SYNC_PPP line disciplines,
ppp_asynctty_receive() and ppp_sync_receive(), call tty_unthrottle()
which may sleep. Fix the comments claiming otherwise.

Impact: documentation

DPRINTF() is used in hw specific related code, as such
ensure we don't rely on the private driver core ath_softc
struct when calling it. Drivers can then implement their
own DPRINTF() as they see fit.

From af03abecd8e3646736904431f3335dad5e28cb8d Mon Sep 17 00:00:00 2001
From: "Luis R. Rodriguez" <lrodriguez@atheros.com>
Date: Wed, 9 Sep 2009 02:33:11 -0700
Subject: ath9k: move hw specific btcoex info to ath_hw

Since we now access it via the ath_hw declare the ath_hw pointer
at the header of some routines and se it. ath9k.h no longer needs to
access btcoex.h and to adjust for this move ath_btcoex_set_weight()
into btcoex.h and instead give main.c a helper for setting initial
values upon drv_start()

Subject: ath9k: move driver core helpers to main.c

Keep on btcoex.c only hardware access helpers, move the
driver core specific code to main.c. To accomplish
this we had to split ath_init_btcoex_info() into two parts,
the driver core part -- ath_init_btcoex_timer() and the hw
specific part -- ath9k_hw_init_btcoex_hw_info(). This
highlights how ath_gen_timer is part of the driver core, not
hw related, so stuff that into ath_btcoex struct.

The ath9k_hw_btcoex_init() code is now put inline on
ath_init_softc() through a switch to it easier to follow,
since we did that we can now call ath_tx_get_qnum() from
the main.c instead of btcoex.c

Subject: ath9k: replaces SC_OP_BTCOEX_ENABLED with a bool

Whether or not bluetooth coex has been enabled is a hardware
state and only the hardware helpers will be able to set this.

Subject: ath9k: move bt_stomp_type to driver core

The bt_stomp_type defines the bt coex weight, it has a one-to-one
mapping. In the future we may want to just use the weight directly.

From 269ad8120b2e1f01a7bcea4bdb175142a0e62171 Mon Sep 17 00:00:00 2001
From: "Luis R. Rodriguez" <lrodriguez@atheros.com>
Date: Wed, 9 Sep 2009 15:05:00 -0700
Subject: ath9k: simplify ath_btcoex_bt_stomp()

The second argument is always the hardware bt coex struct, so
remove it, and rename the function on the path with a ath9k_ prefix.

Subject: ath9k: move ps helpers onto core driver when reseting tsf

When the TSF is reset power save state is disabled and
then restored. The helpers to disable power save and restore
it use a lock provided by the driver core. Move the callers
of the helpers outside of the hw code.

We reset the TSF when mac80211 tells us and on the beacon.c
helper ath9k_hw_beaconinit() when it is made explicitly required.
Add a helper on beacon.c which will deal with ps awake/restore
if we need to reset the TSF upon ath9k_hw_beaconinit().

Subject: ath9k: avoid usage of ath9k_hw_setpower() on hw.c

ath9k_hw_setpower() is a core driver helper with locking
protection. Locking protection should be left to the driver
core, not the hw code. Hardware code no longer contends for
locking when it needs to wake up the chip or put it to sleep.

Subject: atheros: use get_unaligned_le*() for bssid mask setting

Historically some macro helpers have been users for this,
AR5K_LOW_ID() and AR5K_HIGH_ID(), use upstream unaligned
helpers instead. This applid to ath5k and ar9170. ath9k
already uses this.

Worth noting is ath5k uses an ah_sta_id but that is already
the MAC address combined with the associaiton ID, ah_sta_id
is really ETH_ALEN in size.

and curbssid. We'll change ath5k and ar9170 separately.

Subject: ath5k: use common curbssid, bssidmask and macaddr

The ah_sta_id was really being used as the macaddr.
ath5k still does not use the association ID now passed
up by mac80211, that can be fixed later.

Subject: ath9k: Define bus agnostic bluetooth coex prep helper

We disable ASPM when enabling bluetooth coexistance. Disabling
ASPM is a bus specific operation. In the future other buses may
support bluetooth coexistance, an example is USB. To this end
move the current routine which disables ASPM into pci.c, and declare
it the PCI bt_coex_prep() helper. Additionally, since ASPM is
a PCI-Express primitive ensure we don't ever try to muck with ASPM
registers on non PCI-express devices.

This also cleans up hw.c to not include bus specific headers or
utilities.

Subject: atheros/ath9k: add common read/write ops and port ath9k to use it

In an effort to make hw code driver core agnostic read
and write operations are defined on the ath_common structure.
This patch adds that and makes ath9k use it. This allows
drivers like ath9k_htc to define its own read/write ops and
still rely on the same hw code. This also paves the way for
sharing code between ath9k/ath5k/ath9k_htc.

Subject: ath5k: allocate ath5k_hw prior to initializing hw

We can propagate better errors upon failed hw initialization,
and set up the ath_common structure for attach purposes. This
will become important once we start using the ath_common
for read/write ops.

-/**
- * ath5k_hw_set_bssid_mask - filter out bssids we listen
- *
- * @ah: the &struct ath5k_hw
- * @mask: the bssid_mask, a u8 array of size ETH_ALEN
- *
- * BSSID masking is a method used by AR5212 and newer hardware to inform PCU
- * which bits of the interface's MAC address should be looked at when trying
- * to decide which packets to ACK. In station mode and AP mode with a single
- * BSS every bit matters since we lock to only one BSS. In AP mode with
- * multiple BSSes (virtual interfaces) not every bit matters because hw must
- * accept frames for all BSSes and so we tweak some bits of our mac address
- * in order to have multiple BSSes.
- *
- * NOTE: This is a simple filter and does *not* filter out all
- * relevant frames. Some frames that are not for us might get ACKed from us
- * by PCU because they just match the mask.
- *
- * When handling multiple BSSes you can get the BSSID mask by computing the
- * set of  ~ ( MAC XOR BSSID ) for all bssids we handle.
- *
- * When you do this you are essentially computing the common bits of all your
- * BSSes. Later it is assumed the harware will "and" (&) the BSSID mask with
- * the MAC address to obtain the relevant bits and compare the result with
- * (frame's BSSID & mask) to see if they match.
- */
-/*
- * Simple example: on your card you have have two BSSes you have created with
- * BSSID-01 and BSSID-02. Lets assume BSSID-01 will not use the MAC address.
- * There is another BSSID-03 but you are not part of it. For simplicity's sake,
- * assuming only 4 bits for a mac address and for BSSIDs you can then have:
- *
- *                  \
- * MAC:        0001 |
- * BSSID-01:   0100 | --> Belongs to us
- * BSSID-02:   1001 |
- *                  /
- * -------------------
- * BSSID-03:   0110  | --> External
- * -------------------
- *
- * Our bssid_mask would then be:
- *
- *             On loop iteration for BSSID-01:
- *             ~(0001 ^ 0100)  -> ~(0101)
- *                             ->   1010
- *             bssid_mask      =    1010
- *
- *             On loop iteration for BSSID-02:
- *             bssid_mask &= ~(0001   ^   1001)
- *             bssid_mask =   (1010)  & ~(0001 ^ 1001)
- *             bssid_mask =   (1010)  & ~(1001)
- *             bssid_mask =   (1010)  &  (0110)
- *             bssid_mask =   0010
- *
- * A bssid_mask of 0010 means "only pay attention to the second least
- * significant bit". This is because its the only bit common
- * amongst the MAC and all BSSIDs we support. To findout what the real
- * common bit is we can simply "&" the bssid_mask now with any BSSID we have
- * or our MAC address (we assume the hardware uses the MAC address).
- *
- * Now, suppose there's an incoming frame for BSSID-03:
- *
- * IFRAME-01:  0110
- *
- * An easy eye-inspeciton of this already should tell you that this frame
- * will not pass our check. This is beacuse the bssid_mask tells the
- * hardware to only look at the second least significant bit and the
- * common bit amongst the MAC and BSSIDs is 0, this frame has the 2nd LSB
- * as 1, which does not match 0.
- *
- * So with IFRAME-01 we *assume* the hardware will do:
- *
- *     allow = (IFRAME-01 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
- *  --> allow = (0110 & 0010) == (0010 & 0001) ? 1 : 0;
- *  --> allow = (0010) == 0000 ? 1 : 0;
- *  --> allow = 0
- *
- *  Lets now test a frame that should work:
- *
- * IFRAME-02:  0001 (we should allow)
- *
- *     allow = (0001 & 1010) == 1010

+/**
+ * ath_hw_set_bssid_mask - filter out bssids we listen
+ *
+ * @common: the ath_common struct for the device.
+ *
+ * BSSID masking is a method used by AR5212 and newer hardware to inform PCU
+ * which bits of the interface's MAC address should be looked at when trying
+ * to decide which packets to ACK. In station mode and AP mode with a single
+ * BSS every bit matters since we lock to only one BSS. In AP mode with
+ * multiple BSSes (virtual interfaces) not every bit matters because hw must
+ * accept frames for all BSSes and so we tweak some bits of our mac address
+ * in order to have multiple BSSes.
+ *
+ * NOTE: This is a simple filter and does *not* filter out all
+ * relevant frames. Some frames that are not for us might get ACKed from us
+ * by PCU because they just match the mask.
+ *
+ * When handling multiple BSSes you can get the BSSID mask by computing the
+ * set of  ~ ( MAC XOR BSSID ) for all bssids we handle.
+ *
+ * When you do this you are essentially computing the common bits of all your
+ * BSSes. Later it is assumed the harware will "and" (&) the BSSID mask with
+ * the MAC address to obtain the relevant bits and compare the result with
+ * (frame's BSSID & mask) to see if they match.
+ *
+ * Simple example: on your card you have have two BSSes you have created with
+ * BSSID-01 and BSSID-02. Lets assume BSSID-01 will not use the MAC address.
+ * There is another BSSID-03 but you are not part of it. For simplicity's sake,
+ * assuming only 4 bits for a mac address and for BSSIDs you can then have:
+ *
+ *                  \
+ * MAC:        0001 |
+ * BSSID-01:   0100 | --> Belongs to us
+ * BSSID-02:   1001 |
+ *                  /
+ * -------------------
+ * BSSID-03:   0110  | --> External
+ * -------------------
+ *
+ * Our bssid_mask would then be:
+ *
+ *             On loop iteration for BSSID-01:
+ *             ~(0001 ^ 0100)  -> ~(0101)
+ *                             ->   1010
+ *             bssid_mask      =    1010
+ *
+ *             On loop iteration for BSSID-02:
+ *             bssid_mask &= ~(0001   ^   1001)
+ *             bssid_mask =   (1010)  & ~(0001 ^ 1001)
+ *             bssid_mask =   (1010)  & ~(1001)
+ *             bssid_mask =   (1010)  &  (0110)
+ *             bssid_mask =   0010
+ *
+ * A bssid_mask of 0010 means "only pay attention to the second least
+ * significant bit". This is because its the only bit common
+ * amongst the MAC and all BSSIDs we support. To findout what the real
+ * common bit is we can simply "&" the bssid_mask now with any BSSID we have
+ * or our MAC address (we assume the hardware uses the MAC address).
+ *
+ * Now, suppose there's an incoming frame for BSSID-03:
+ *
+ * IFRAME-01:  0110
+ *
+ * An easy eye-inspeciton of this already should tell you that this frame
+ * will not pass our check. This is beacuse the bssid_mask tells the
+ * hardware to only look at the second least significant bit and the
+ * common bit amongst the MAC and BSSIDs is 0, this frame has the 2nd LSB
+ * as 1, which does not match 0.
+ *
+ * So with IFRAME-01 we *assume* the hardware will do:
+ *
+ *     allow = (IFRAME-01 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
+ *  --> allow = (0110 & 0010) == (0010 & 0001) ? 1 : 0;
+ *  --> allow = (0010) == 0000 ? 1 : 0;
+ *  --> allow = 0
+ *
+ *  Lets now test a frame that should work:
+ *
+ * IFRAME-02:  0001 (we should allow)
+ *
+ *     allow = (0001 & 1010) == 1010
+ *
+ *     allow = (IFRAME-02 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
+ *  --> allow = (0001 & 0010) ==  (0010 & 0001) ? 1 :0;
+ *  --> allow = (0010) == (0010)
+ *  --> allow = 1
+ *
+ * Other examples:
+ *
+ * IFRAME-03:  0100 --> allowed
+ * IFRAME-04:  1001 --> allowed
+ * IFRAME-05:  1101 --> allowed but its not for us!!!

Subject: atheros: add common debug printing

ath9k uses this for now, ath9k_htc is expected to re-use this
as well. We lave ath5k as is, but it certainly can also be
converted later.

The ath9k module parameter and debugfs entry is kept.

Subject: ath9k: remove ath9k 25 MHz HT40 spacing stuff

This was for supporting 25 MHz spacing for HT40, this is not used
as we use 20 MHz spacing instead for HT40 as per 802.11n. The hardware
is capable of it though so we leave the phymode definition and EEPROM
parsing for it. If some experimenter wants to work on this stuff stuff
you can add an extension enabling bool on ath_common and perhaps some
debugfs knob to enable it. Keep in mind you'll also need to update the
phymode with the AR_PHY_FC_DYN2040_EXT_CH which has been left on the
driver.

From 25c56eec92b15fdec5be96fa1303dac3443200ae Mon Sep 17 00:00:00 2001
From: "Luis R. Rodriguez" <lrodriguez@atheros.com>
Date: Sun, 13 Sep 2009 23:04:44 -0700
Subject: ath9k: remove ath9k_ht_macmode

This is used just to determine how to program the MAC,
either for 20 MHz operation of 40 MHz so just use conf_is_ht40()

From cfe8cba982cda73d4970dab712411bebdcc3b9cd Mon Sep 17 00:00:00 2001
From: "Luis R. Rodriguez" <lrodriguez@atheros.com>
Date: Sun, 13 Sep 2009 23:39:31 -0700
Subject: ath9k: clarify what hw code is and remove ath9k.h from a few files

hw code will be shared between ath9k and ath9k_htc.
Just a few more files are left to clean up, mark them as well.

This is the last part to make ath9k hw code core driver agnostic.
I believe ath9k_htc can now use use the hw code unmodified.

Subject: iwlwifi: separate nic_config for different NIC

Different NIC has different requirements for configuration. Currently all
5000 series hardware and later share the same configuration function even
though they do not need the same configurations. Fix this by separating the
needed configuration actions for each hardware model.

.5000 series: L1-ASPM H/W bug work-around
              configure radio
              write CSR_HW_IF_CONFIG_REG for uCode use
              work-around for NIC get stuck after early PCIe power off

.1000 series: write CSR_HW_IF_CONFIG_REG for uCode use
              setting digital SVR for 1000 card to 1.32V

.6000 series: configure radio
              write CSR_HW_IF_CONFIG_REG for uCode use
              write CSR_GP_DRIVER_REG to indicate radio sku

Subject: iwlwifi: separate set_hw_params function for 6000 series

Separate set_hw_params() function for 6000
series from 5000/1000 series because:
    1) 6000 series use different set of sensitivity range table
    2) 6000 series has different uCode image size

Also include the new sensitivity parameters needed by sensitivity
algorithm.

is_ht can be bool instead of u8, and there's
no need to use IWL_CHANNEL_WIDTH_* constants

Subject: iwlwifi: Adjust blink rate to compensate Clock difference

Adjust led blink rate to compensate on a MAC Clock difference on every
HW. Led blink rate analysis showed an average deviation of 0% on 3945,
5% on 4965 HW and 20% on 5000 series and up.
Need to compensate on the led on/off time per HW according to the
deviation to achieve the desired led frequency
The calculation is: (100-averageDeviation)/100 * blinkTime
For code efficiency the calculation will be:
    compensation = (100 - averageDeviation) * 64 / 100
    NewBlinkTime = (compensation * BlinkTime) / 64

Subject: iwlwifi: clean up ht config naming

Daniel Halperin pointed out that the naming
here is rather inconsistent with at least 3
different names being used for one thing in
different contexts. Rename the struct to
iwl_ht_config (rather than iwl_ht_info) and
use ht_conf as a variable for it.

Subject: iwlwifi: clarify and clean up chain settings

The chain settings we currently use in iwlwifi are
rather confusing -- and we also go by the wrong
settings entirely under certain circumstances. To
clean it up, create a new variable in the current
HT config -- single_chain_sufficient -- that tells
us whether we need more than one chain. Calculate
that based on the AP and operating mode (no IBSS
HT implemented -- so no need for multiple chains,
for station mode we use the AP's capabilities).

Additionally, since APs always send disabled SM PS
mode, keeping track of their sm_ps mode isn't very
useful -- doubly not so for our _own_ RX config
since that should depend on our, not the AP's, SM
PS mode.

Finally, document that our configuration of the
number of RX chains used is currently wrong when
in powersave (by adding a comment).

All together this removes the two remaining items
in struct iwl_ht_config that were done wrong there.

For the future, the number of RX chains and some
SM PS handshaking needs to be added to mac80211,
which then needs to tell us, and the new variable
current_ht_config.single_chain_sufficient should
also be calculated by mac80211.

Subject: iwlwifi: Use RTS/CTS as the preferred protection mechanism for 6000
 series

When 802.11g was introduced, we had RTS/CTS and CTS-to-Self protection
mechanisms. In an HT Beacon, HT stations use the "Operating Mode" field
in the HT Information Element to determine whether or not to use
protection.

The Operating Mode field has 4 possible settings: 0-3:
Mode 0: If all stations in the BSS are 20/40 MHz HT capable, or if the
BSS is 20/40 MHz capable, or if all stations in the BSS are 20 MHz HT
stations in a 20 MHz BSS
Mode 1: used if there are non-HT stations or APs using the primary or
secondary channels
Mode 2: if only HT stations are associated in the BSS and at least one
20 MHz HT station is associated.
Mode 3: used if one or more non-HT stations are associated in the BSS.

When in operating modes 1 or 3, and the Use_Protection field is 1 in the
Beacon's ERP IE, all HT transmissions must be protected using RTS/CTS or
CTS-to-Self.

By default, CTS-to-self is the preferred protection mechanism for less
overhead and higher throughput; but using the full RTS/CTS will better
protect the inner exchange from interference, especially in
highly-congested environment.

For 6000 series WIFI NIC, RTS/CTS protection mechanism is the
recommended choice for HT traffic based on the HW design.

Subject: iwlwifi: add aggregation tables to the rate scaling algorithm

Current rate scale algorithm fluctuates between different MIMO modes fairly
rapidly, causing widely varying performance. These fluctuations occur because in
the rate_scale tables for expected throughput the values are not very different
for different modes.

However, when aggregation is turned on and MAC overhead is reduced, the
expected throughput for different MIMO modes grows and different modes have
vastly different performance. Add expected throughput tables for this case.

We also need to keep track of aggregation status per-station, so we add the
"is_agg" field to struct lq_sta.

Also includes cleanup of comments and variable names in/around the affected
code.

Subject: iwlwifi: add LED mode to support different LED behavior

Today's implementation allow LED to blink based on the traffic
condition. We introduce an additional LED mode that reflects the RF
state.

The supported LED modes after this are:
  IWL_LED_BLINK (current/default) - blink rate based on current Tx/Rx
                                    traffic
  IWL_LED_RF_STATE (new) -
    LED OFF: No power/RF disabled, the LED is emitting no light
    LED ON:  Powered/RF enabled, the LED is emitting light
             in a stable non-flashing state.

In order to provide the flexibility to support different LED
behavior per user/system preference we add "led_mode" iwlcore module
parameter.

Subject: iwlwifi: default to using all chains

When instructing the microcode to use just a single
chain when we have power saving enabled, we should
also tell the AP that we are doing SM powersave.
However, using a single chain doesn't actually have
any power saving advantage while idle -- measurements
show that the power consumption is no different when
using one vs. two or three chains.

Therefore, always instruct the microcode to use all
chains.

Subject: iwlwifi: support idle for 6000 series hw

Using powersave while idle saves a lot of power, but
we've had problems with this on some cards (5150 has
been reported to be problematic). However, on the new
6000 series we're seeing no problems, so for now let
that hardware benefit from idle mode, we can look at
the problems with other hardware one by one and then
enable those once we figure out the problems.

Subject: ath9k: Update INI release for AR9287

If the current channel is between 2412 and 2472 MHz and if the channel is
changing to 2484 MHz, then the registers 0xa1f4, 0xa1f8 and 0xa1fc need to be
programmed to the "japan_2484" values.  Conversely, if the current channel
is 2484 MHz and if the channel is changing to one between 2412 and 2472 MHz, then
the three registers need to be programmed to the "normal" values.

This is needed for compliance with Japanese regulatory requirements.

Subject: ath9k: Fix RTC reset for AR5416

For AR5416 chipsets, clearing RTC_RESET_EN when setting
the chip to SLEEP mode results in high power consumption.
This patch fixes this issue by not clearing it for AR5416.

Reduce PLL Settle time and eliminate redundant PLL calls. Also reduce
the LoadNF timeout from 10 msec to 250usec as the 10 msec timeout was
hit with AR9285 in some cases.

Subject: ath9k: Fix bugs in handling TX power

* Get power table offset from the EEPROM instead of using
  a hardcoded value of -5 if the EEPROM rev is >= 21.
* Add support in the 4k eeprom code for tx power offset
  in case we have a 4k AR9280 implementation.
* Fix tx power accuracy at high powers.

Subject: iwlwifi: drop lib80211 dependency

Ever since Johannes' "iwlwifi: improve scan support" iwlwifi
no longer needs any of lib80211's functions or definitions.

This patch updates iwlwifi's Kconfig _selections_ and
removes all left lib80211.h inclusions from the source files.

Subject: ath9k: move hw code to its own module

hw code for Atheros 802.11n hardware is commmon between
different chipsets. This moves this code into a separate
module, the next expected user of this code will be
the ath9k_htc module.

The ath9k/ dir is now selected by ATH9K_HW, an option which
gets selected by either ath9k or ath9k_htc, but remains
invisible for user menuconfig configuration. If either
ath9k or ath9k_htc will be compiled into the kernel
ath9k_hw will also be compiled in.

Subject: atheros: define a common priv struct

hw code should never use private driver data, but
sometimes we need a backpointer so just stuff it on
the common ath struct.

From 3d23e349d807177eaf519d444677cee86b1a04cf Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes@sipsolutions.net>
Date: Tue, 29 Sep 2009 23:27:28 +0200
Subject: wext: refactor

Refactor wext to
 * split out iwpriv handling
 * split out iwspy handling
 * split out procfs support
 * allow cfg80211 to have wireless extensions compat code
   w/o CONFIG_WIRELESS_EXT

After this, drivers need to
 - select WIRELESS_EXT	- for wext support
 - select WEXT_PRIV	- for iwpriv support
 - select WEXT_SPY	- for iwspy support

except cfg80211 -- which gets new hooks in wext-core.c
and can then get wext handlers without CONFIG_WIRELESS_EXT.

Wireless extensions procfs support is auto-selected
based on PROC_FS and anything that requires the wext core
(i.e. WIRELESS_EXT or CFG80211_WEXT).

From 125b181aec7a67c71234284ecf6d9c729d05deda Mon Sep 17 00:00:00 2001
From: Larry Finger <Larry.Finger@lwfinger.net>
Date: Thu, 1 Oct 2009 13:22:27 -0500
Subject: staging: Add proper selection of WIRELESS_EXT and WEXT_PRIV

After the incorporation of the patch entitled "wext: refactor", some
of the wireless drivers in drivers/staging fail to build because they
need to have CONFIG_WIRELESS_EXT and CONFIG_WEXT_PRIV defined.

Subject: libertas: Add auto deep sleep support for SD8385/SD8686/SD8688

Add timer based auto deep sleep feature in libertas driver which can be
configured using iwconfig command. This is tested on SD8688, SD8686 cards
with firmware versions 10.38.1.p25, 9.70.4.p0 respectively on 32-bit and 64-bit
platforms. Tests have been done for USB/CS cards to make sure that the patch
won't break USB/CS code. We didn't test the if_spi driver.

+
+	This command is used to configure the station in deep sleep mode /
+	auto deep sleep mode.
+
+	The timer is implemented to monitor the activities (command, event,
+	etc.). When an activity is detected station will exit from deep
+	sleep mode automatically and restart the timer. At timer expiry
+	(no activity for defined time period) the deep sleep mode is entered
+	automatically.
+
+	Note: this command is for SDIO interface only.
+
+	Usage:
+	To enable deep sleep mode do:
+		iwconfig wlan0 power period 0
+	To enable auto deep sleep mode with idle time period 5 seconds do:
+		iwconfig wlan0 power period 5
+	To disable deep sleep/auto deep sleep mode do:

From 7812b16730ccebce71a3b2228ac08dd4f8b39469 Mon Sep 17 00:00:00 2001
From: Wey-Yi Guy <wey-yi.w.guy@intel.com>

Subject: iwlwifi: reliable entering of critical temperature state

When uCode detects critical temperature it should send "card state
notification" interrupt to driver and then shut itself down to prevent
overheating. There is a race condition where uCode shuts down before it
can deliver the interrupt to driver.
Additional method provided here for driver to enter CT_KILL state based
on temperature reading.

How it works:
Method 1:
If driver receive "card state notification" interrupt from uCode; it
enters "CT_KILL" state immediately

Method 2:
If the last temperature report by Card reach Critical temperature,
driver will send "statistic notification" request to uCode to verify the
temperature reading, if driver can not get reply from uCode within
300ms, driver will enter CT_KILL state automatically.

Method 3:
If the last temperature report by Card did not reach Critical
temperature, but uCode already shut down due to critical temperature.
All the host commands send to uCode will not get process by uCode;
when command queue reach the limit, driver will check the last reported
temperature reading, if it is within pre-defined margin, enter "CT_KILL"
state immediately. In this case, when uCode ready to exit from "CT_KILL" state,
driver need to restart the adapter in order to reset all the queues and
resume normal operation.

One additional issue being address here, when system is in CT_KILL
state, both tx and rx already stopped, but driver still can send host
command to uCode, it will flood the command queue since card was not
responding; adding STATUS_CT_KILL flag to reject enqueue host commands
to uCode if it is in CT_KILL state, when uCode is ready to come out of
CT_KILL, driver will clear  the STATUS_CT_KILL bit and allow enqueue the host
commands to uCode to recover from CT_KILL state.

Subject: iwlwifi: set default aggregation frame count limit to 31

Multiple MPDUs can be aggregated, transmitted, and finally acknowledged
together using a single BA frame. Block ACK (BA) contains
bitmap size of 64*16 bits so the maximum frame count is 64.
The default value of aggregation frame count suggested by uCode is 31 to
achieve best performance.

Subject: iwlwifi: device tracing

In order to have an easier way to debug issues, create
trace events (using the ftrace framework) that will
allow us to follow exactly what the driver is doing
with the device.

The text format isn't all that useful, but the binary
format can also be obtained easily via debugfs and
then analysed on the fly or offline with debugging
tools.

From e932a609e9759cc75db0c234f465a5fd6e20d362 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes@sipsolutions.net>
Date: Fri, 2 Oct 2009 13:44:03 -0700
Subject: iwlwifi: LED cleanup

The iwlwifi drivers have LED blinking requirements that
mac80211 cannot fulfill due to the use of just a single
LED instead of different ones for TX, RX, radio etc.
Instead, the single LED blinks according to transfers
and is solid on the rest of the time. As such, having
LED class devices registered that mac80211 triggers are
connected to is pointless as we don't use the triggers
anyway.

Remove all the useless code and add hooks into the
driver itself. At the same time, make the LED code
abstracted so the core code that determines blink rate
etc. can be shared between 3945 and agn in iwlcore.

At the same time, the fact that we removed the use of
the mac80211 LED triggers means we can also remove the
IWLWIFI_LEDS Kconfig symbol since the LED support is
now self-contained.

Subject: iwlwifi: replace iwl_poll_direct_bit with iwl_poll_bit for CSR access

Replace iwl_poll_direct_bit with iwl_poll_bit when accessing CSR registers.
There is no need to power up the mac to access CSR registers.

Subject: iwlwifi: validate the signature for EEPROM and OTP

Both 1000 & 6000 series NICs contain on-chip OTP memory that
replaces the off-chip EEPROM memory. The nature of OTP means
there is a limited number of times a particular board can go through the
factory flow and be (re)calibrated. As a consequence there will be some boards
that contain EEPROM memory because OTP blocks were full.

In the signature validation routine, iwlwifi needs to make sure
"select bit" and "EEPROM/OTP signature" agree on the type of
NVM to be used to configure the system.

Subject: ath5k: simplify passed params to ath5k_hw_set_associd()

We have access to common->curbssid and common->curaid so just
use those. Note that common->curaid is always 0 so this keeps
our current behaviour of always using 0 for now. Once we fix
storing the association ID passed by mac80211 this will
require no changes here.

Subject: ath9k: initialize hw prior to debugfs

debugfs uses the hardware for several debugfs files as such the
hardware must be initialized and available prior to its usage. The
same applies to when we free the hw structs -- free debufs file
entries prior to free'ing the hardware.

Subject: ath9k: add a helper to clean the core driver upon module unload

The core driver needs to be stopped and then as a last step the
hardware needs to be stopped and its structure free'd. We do this
by moving the core driver cleanup to a new helper ath_clean_core()
and have ath_cleanup() call it. Only as a last step does
ath_cleanup() now free the hw.

From 63f275df64dc69a46bbc21e6a68d5506d2da9c51 Mon Sep 17 00:00:00 2001
From: Amitkumar Karwar <akarwar@marvell.com>
Date: Tue, 6 Oct 2009 19:20:28 -0700
Subject: libertas: Use lbs_is_cmd_allowed() check in command handling
 routines.

lbs_is_cmd_allowed() check is added in __lbs_cmd_async() and
lbs_prepare_and_send_command(). The check is removed from other places.

Subject: bonding: fix a parameter name in error message
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When parsing module parameters, bond_check_params() erroneously use
'xor_mode' as the name of a module parameter in an error message.

The right name for this parameter is 'xmit_hash_policy'.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The variable old_active is first set to bond->curr_active_slave.
Then, it is unconditionally set to new_active, without being used in between.

The first assignment, having no side effect, is useless.

Subject: ixgbe: Fix KR to KX fail over for Mezzanine cards

This patch allows the recently added backplane device IDs that support KR
to fail over to KX during link setup.  This is accomplished by the new MAC
link setup function ixgbe_setup_mac_link_smartspeed().  Comments were also
updated to better document the reason for the delays chosen for KX, KX4, BX,
BX4 and KR connections.

Subject: wireless: make wireless drivers select core

It is somewhat non-sensical to allow selecting wireless
drivers without showing wireless core code options, and
since the wext refactoring this has made it possible to
generate configurations that will not build. Avoid this
and make wireless drivers select the wireless options.

Subject: gianfar: Some cleanups for startup_gfar()

We're going to split the startup_gfar() into 3 separate functions,
so let's cleanup the code a little bit so that cosmetic changes
won't distract attention from logical ones.

- Remove needless casts (e.g. (struct sk_buff **)kmalloc());
- Turn 'unsigned long vaddr;' into 'void *vaddr', to avoid casting;
- Add new 'struct device *dev' variable as a shorthand for
  '&priv->ofdev->dev' that is used all over the place, also rename
  'struct net_device *dev' to 'struct net_device *ndev';
- Turn printk(KERN_ERR ...) to pr_err(...), which is shorter;
- Don't return bogus -1 (i.e. -EPERM) when request_irq() fails;
- Turn '&priv->regs->' to just '&regs->'.

Subject: gianfar: Simplify skb resources freeing code

Remove dma_free_coherent() from stop_gfar() and gfar_start() calls,
place it into free_skb_resources(). That makes SKB resources management
more understandable, plus free_skb_resources() will be used as a cleanup
routine for gfar_alloc_skb_resources() that will be implemented soon.

Subject: gianfar: Don't needlessly set the wrap bit for the last RX BD

startup_gfar() sets the wrap bit for the last rxbd just after
gfar_new_rxbdp() call, which is issued for all rxbds. And
gfar_new_rxbdp() has the following check already:

	if (bdp == priv->rx_bd_base + priv->rx_ring_size - 1)
		lstatus |= BD_LFLAG(RXBD_WRAP);

So we don't need to set the bit again.

Subject: gianfar: Split allocation and initialization steps out of
 startup_gfar()

Two new functions implemented: gfar_alloc_skb_resources() and
gfar_init_mac(). We'll use gfar_init_mac() for restoring after
hibernation.

The patch just moves the code around, there should be no functional
changes.

Subject: gianfar: Move tbase/rbase initialization to gfar_init_mac()

For hibernation we want to call gfar_init_mac() without need to
free/allocate_skb_resources sequence, so save the DMA address into a
private struct, and move tbase/rbase initialization to gfar_init_mac().

Subject: gianfar: Factor out gfar_init_bds() from gfar_alloc_skb_resources()

After hibernation we want to just reinitialize BDs, no need to allocate
anything. So, factor out BDs initialization code from
gfar_alloc_skb_resourses().

Also, teach gfar_init_bds() to reuse already allocated RX SKBs, i.e.
just call gfar_init_rxbdp() if a SKB was already allocated and mapped.

Subject: gianfar: Add support for hibernation

Thanks to various cleanups and refactorings this is now straightforward:
convert the gianfar driver to dev_pm_ops, plus add ->restore() callback
that will fully reinitialize MAC internal registers and BDs.

Note that I kept legacy suspend/resume callbacks so that this patch
doesn't depend on PowerPC changes (i.e. dev_pm_ops support for OF
platform drivers).

Subject: mdio: Advertise pause (flow control) settings even if autoneg is off

Currently, if pause autoneg is off we do not set either pause
advertising flag.  If autonegotiation of speed and duplex settings is
enabled, there is no way for the link partner to distinguish this from
our refusing to use pause frames.

We should instead set the advertising flags according to the forced
mode so that the link partner can follow our lead.  This is consistent
with the behaviour of other drivers.

Subject: bonding: change bond_create_proc_entry() to return void
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The function bond_create_proc_entry is currently of type int.

Two versions of this function exist:

The one in the ifdef CONFIG_PROC_FS branch always return 0.
The one in the else branch (which is empty) return nothing.

When CONFIG_PROC_FS is undef, this cause the following warning:

drivers/net/bonding/bond_main.c: In function `bond_create_proc_entry':
drivers/net/bonding/bond_main.c:3393: warning: control reaches end of
non-void function

No caller of this function use the returned value.

So change the returned type from int to void and remove the
useless return 0; .

Subject: can: make the number of echo skb's configurable

This patch allows the CAN controller driver to define the number of echo
skb's used for the local loopback (echo), as suggested by Kurt Van
Dijck, with the function:

  struct net_device *alloc_candev(int sizeof_priv,
                                  unsigned int echo_skb_max);

The CAN drivers have been adapted accordingly. For the ems_usb driver,
as suggested by Sebastian Haas, the number of echo skb's has been
increased to 10, which improves the transmission performance a lot.

Subject: cxgb3: Added private MAC address and provisioning packet handler for
 iSCSI

This patch added support of private MAC address per port and provisioning
packet handler for iSCSI traffic only.

The above changes are isolated to the cxgb3 driver, independent of any scsi or iscsi driver changes.

Sub 64-bit / unaligned access to oncard memory was only used
by old diagnostic tools, causes some intermittent issues when
memory controller agent is used.  The new access method was
added by commit ea6828b8aa3a8ebae8d7740f32f212ba1d2f0742
("netxen: improve pci memory access").  Firmware init anyway
uses 8-byte strides.

This also fixes address/offset calculation for NX2031 context
memory (SIU). For NX3031, SIU uses same register offsets
as packet memory (MIU).

Subject: netxen: separate register and memory access lock

Since register and onboard memory access has separate
window registers, they need not be kept under same lock.

Also, memory is always accessed from process context
(mostly for firmware init and diagnostic tools).

Subject: ixgbe: Fix erroneous display of stats by ethtool -S

Commit 59aa3cc4 overlooked the way offsets for netdev stats were considered.
Because of this some of the stats shown by ethtool -S were wrong.
This patch fixes it.

Subject: igb: Fix erroneous display of stats by ethtool -S

Commit 337e067d overlooked the way offsets for netdev stats were considered.
Because of this some of the stats shown by ethtool -S were wrong.
This patch fixes it.

Subject: net: Remove BKL from tun

The lock_kernel/unlock_kernel() in cycle_kernel_lock() which is called
in tun_chr_open() is not serializing against anything and safe to
remove.

tun_chr_fasync() is serialized by get/put_tun() and fasync_helper()
has no dependency on BKL. The modification of tun->flags is racy with
and without the BKL so removing it does not make it worse.

Subject: bnx2x: Allowing 0 as initial fairness value

Value of zero was used to disable the fairness mechanism. Though the code
(driver and FW) allowed changing the value at run time, it did not allow to do
that if the mechanism was disabled to begin with.
Fixed the FW to allow turning on and off the mechanism at run time. Fixed the
code to read the value from the chip at the right sequence.
Without this fix, if the initial value was set to zero, traffic could not run on
the interface.

Subject: bnx2x: Changing the Disabled state to a flag

When working with DCC, a function can be disabled or enabled (virtual link down
or up). Using the function state introduced some race conditions with the
load/unload flow.
Using a separate flag to indicate that the function is disabled.

Subject: netxen: sysfs control for auto firmware recovery

Firmware hang detection and recovery (reset) need to
be disabled for diagnostic tools, which can run
some disruptive tests.

This adds a driver level control to turn off this
feature by diag tools.

Timer_list structure in lcs_send_lancmd() is allocated on stack.
Initialization with init_timer() leads to above ODEBUG message.
Instead use init_timer_on_stack() which prevents above msg.

The creation of a new lcs device requires a call to the function
ccw_device_set_online() for the read and the write channel. Failure
of either call should terminate the lcs device creation immediately
with return code -ENODEV.

Subject: inet: rename some inet_sock fields

In order to have better cache layouts of struct sock (separate zones
for rx/tx paths), we need this preliminary patch.

Goal is to transfert fields used at lookup time in the first
read-mostly cache line (inside struct sock_common) and move sk_refcnt
to a separate cache line (only written by rx path)

This patch adds inet_ prefix to daddr, rcv_saddr, dport, num, saddr,
sport and id fields. This allows a future patch to define these
fields as macros, like sk_refcnt, without name clashes.

Subject: wimax/i2400m: fix the bootmode RX deadlock in SDIO driver

i2400ms_bus_bm_wait_for_ack() causes a race condition. It happens
because this function clears i2400ms->bm_ack_size before waiting for
an interrupt, which is set by the interrupt service routine i2400ms_rx()
to indicate reception and size of received data; thus, if the interrupt
came right before the clearing/waiting, it is lost.

The fix is clear the bm_ack_size to -EINPROGRESS before we are enabling
the RX interrupt configuration in i2400ms_rx_setup(). Then everytime
when the interrupt service routine i2400ms_rx() is invoked during bootmode,
bm_ack_size is updated with the actual rx_size and it is cleared to
-EINPROGRESS again after the RX data is handled.

Subject: wimax/i2400m: Make boot retries a BUS-specific parameter

In i2400m-based devices, the driver's bootloader will retry to load
the firmware when things go wrong. The driver currently has a constant
(I2400M_BOOT_RETRIES) which governs the max number of tries.

However, different SKUs of the same hardware may admit or require
different numbers of retries due to it's particulars, so it is made a
BUS specific parameter and different values are assigned for 5x50
devices versus the 3200 ones.

Subject: wimax/iwmc3200: overwrite SDIO IOR timeout value to avoid platform
 hang

The default SDIO IOE wait timeout returned from iwmc3200-wimax's CCCR
is not efficient. This inefficiency will actually cause problems on
Moorestown platforms (system hang).

This is a sillicon bug that requires a software patch to by
overwritting func->enable_timeout. The new value I2400MS_IOR_TIMEOUT
is recommended and verified from the system integration results.

Future sillicon releases will have this default value corrected in the
future.

Subject: wimax/iwmc3200: don't disable the SDIO function if enable fails

In the iwmc3200, disabling the WiMAX SDIO function when enable fails
would possibly result in a device reset triggered by the iwmc3200's
top controller since it monitors the bus reset activities from each
SDIO function. In any case, the disable makes no sense; if the enable
fails, it should not be disabled.

Thus we remove the unecessary sdio_disable_func() in
i2400ms_enable_function().

Subject: wimax/iwmc3200: increase wait time before enable retry

When trying to enable the iwmc3200 WiMAX SDIO function, we loop
waiting for the top controller to be up and running (at which point we
can succesfully enable the function). Between each try we wait for
I2400MS_INIT_SLEEP_INTERVAL ms.

Integration tests have found the current value of 10ms to be too
short; it was upped to 100ms to give more time to the top controller
to be ready.

Newer generations of the i2400m USB WiMAX device use a different

Subject: wimax/i2400m: be smarter about copying command buffer to bm_cmd_buf

Because some underlying bus APIs (like USB) don't like data buffers in
the stack or vmalloced areas, the i2400m driver provides a scratch
buffer (i2400m->bm_cmd_buf) for said low-level drivers to copy command
data to before passing it to said API. This is only used during boot
mode.

However, at some the code was copying the buffer even when the command
was already specified in said buffer. This is ok, but it needs to be
more careful. As thus, change so that:

(a) the copy happens only if command buffer is not the scratch buffer

(b) use memmove() in case there is overlapping

In kernel 2.6.31, the firmware requested to ram could be marked

Subject: wimax/i2400m: during probe, call sdio_disable at most once

In the Intel Wireless Multicomm 3200, the initialization is
orchestrated by a component called Top. This component also monitors
how many times a function is reset (via sdio_disable) to detect
possible issues and will reset the whole multifunction device if any
function triggers a maximum reset level.

During WiMAX's probe, the driver needs to wait for Top to come up
before it can enable the WiMAX function. If it cannot, it will return
-ENODEV and the Top driver will rescan the SDIO bus once done
loading.

Currently, the WiMAX SDIO probe routine was trying a few times before
returning -ENODEV, and this was triggering Top's too-many-resets
detector. This is, in any case, unnecessary because the Top driver will
force the bus rescan when the functions can be probed successfully.

Added then a maxtries argument to i2400ms_enable_func() and set it to
1 when calling from probe. We want to reuse this function instead of
flat calling out sdio_enable_func() to take advantage of hardware
quirk workarounds.

Subject: wimax: allow specifying debug levels as command line option

Add "debug" module options to all the wimax modules (including
drivers) so that the debug levels can be set upon kernel boot or
module load time.

This is needed as currently there was a limitation where the debug
levels could only be set when a device was succesfully
enumerated. This made it difficult to debug issues that made a device
not probe properly.

Subject: wimax/i2400m: decide properly if using signed vs non-signed firmware
 loading

The i2400m based devices can boot two main types of firmware images:
signed and non-signed. Signed images have signature data included that
must match that of a certificate stored in the device.

Currently the code is making the decission on what type of firmware
load (signed vs non-signed) is going to be loaded based on a hardcoded
decission in __i2400m_ack_verify(), based on the barker the device
sent upon boot.

This is not flexible enough as future hardware will emit more barkers;
thus the bit has to be set in a place where there is better knowledge
of what is going on. This will be done in follow-up commits -- however
this patch paves the way for it.

So the querying of the mode is packed into i2400m_boot_is_signed();
the main changes are just using i2400m_boot_is_signed() to determine
the method to follow and setting i2400m->sboot in
i2400m_is_boot_barker(). The modifications in i2400m_dnload_init() and
i2400m_dnload_finalize() are just reorganizing the order of the if
blocks and thus look larger than they really are.

Subject: wimax/i2400m: rework bootrom initialization to be more flexible

This modifies the bootrom initialization code of the i2400m driver so
it can more easily support upcoming hardware.

Currently, the code detects two types of barkers (magic numbers) sent
by the device to indicate the types of firmware it would take (signed
vs non-signed).

This schema is extended so that multiple reboot barkers are
recognized; upcoming hw will expose more types barkers which will have
to match a header in the firmware image before we can load it.

For that, a barker database is introduced; the first time the device
sends a barker, it is matched in the database. That gives the driver
the information needed to decide how to upload the firmware and which
types of firmware to use. The database can be populated from module
parameters.

The execution flow is not altered; a new function
(i2400m_is_boot_barker) is introduced to determine in the RX path if
the device has sent a boot barker. This function is becoming heavier,
so it is put away from the hot reception path [this is why there is
some reorganization in sdio-rx.c:i2400ms_rx and
usb-notifc.c:i2400mu_notification_grok()].

The documentation on the process has also been updated.

All these modifications are heavily based on previous work by Dirk
Brandewie <dirk.brandewie@intel.com>.

Subject: wimax/i2400m: retry loading firmware files in sequence

The i2400m firmware loader is given a list of firmware files to try to
load by the probe() function (which can be different based on the
device's model / generation).

Current code didn't attempt to load, check and try to boot with each
file, but just to try to load if off disk. This is limiting in some
cases, where we might want to try to load a firmware and if it fails
to load onto the device, just fall back to another one.

This changes the behaviour so all files are tried for being loaded
from disk, checked and uploaded to the device until one suceeds in
bringing the device up.

Subject: wimax/i2400m: fix reboot echo/ack barker deadlock

The i2400m based devices can get in a sort of a deadlock some times;
when they boot, they send a reboot "barker" (a magic number) and then
the driver has to echo that same barker to ack reception
(echo/ack). Then the device does a final ack by sending an ACK barker.

The first time this happens, we don't know ahead of time with barker
the device is going to send, as different device models and SKUs will
send different barker depending on the EEPROM programming.

If the device has sent the barker before the driver has been able to
read it, the driver looses, as it doesn't know which barker it has to
echo/ack back. With older devices, we tried a couple of combinations
and that always worked; but now, with adding support for more, in
which we have an unlimited number of new barkers, that is not an
option.

So we rework said case so that when the device gets stuck, we just
cycle through all the known types until one forces the device to send
an ack. Otherwise, the driver gives up and aborts.

Subject: wimax/i2400m: support extended firmware format

The SBCF firmware format has been extended to support extra headers
after the main payload. These extra headers are used to sign the
firmware code with more than one certificate. This eases up
distributing single code images that work in more than one SKU of the
device.

The changes to support this feature will be spread in a series of
commits. This one just adds the support to parse the extra headers and
store them in i2400m->fw_hdrs. Coming changes to the loader code will
use that to determine which header to upload to the device.

The i2400m_fw_check() function now iterates over all the headers and
for each, calls i2400m_fw_hdr_check(), which does some basic checks on
each header. It then stores the headers for the bootloader code to use.

The i2400m_dev_bootstrap() function has been modified to cleanup
i2400m->fw_hdrs when done.

Subject: wimax/i2400m: on firmware upload, select BCF header that matches
 device's request

Devices based on the i2400m emit a "barker" (32 bit unsigned) when
they boot. This barker is used to select, in the firmware file image,
which header should be used to process the rest of the file.

This commit implements said support, completing the series started by
previous commits.

We modify the i2400m_fw_dnload() firmware loading path by adding a
call to i2400m_bcf_hdr_find() [new function], in which the right BCF
header [as listed in i2400m->fw_hdrs by i2400m_fw_check()] is
located. Then this header is fed to i2400m_dnload_init() and
i2400m_dnload_finalize().

The changes to i2400m_dnload_finalize() are smaller than they look;
they add the bcf_hdr argument and use that instead of bcf. Likewise in
i2400m_dnload_init().

Different sdio device IDs are designated to support different intel
wimax silicon sku. The new macro SDIO_DEVICE_ID_IWMC3200_WIMAX_2G5(0x1407)
is added to support iwmc3200 2.5GHz sku.  The existing
SDIO_DEVICE_ID_IWMC3200_WIMAX(0x1402) is for iwmc3200 general sku.

Subject: wimax/i6x50: add Intel WiFi/WiMAX Link 6050 Series support

Add support for the WiMAX device in the Intel WiFi/WiMAX Link 6050
Series; this involves:

 - adding the device ID to bind to and an endpoint mapping for the
   driver to use.

 - at probe() time, some things are set depending on the device id:

   + the list of firmware names to try

   + mapping of endpoints

Subject: wimax/i2400m: clean up & add a payload argument to
 i2400m_schedule_work()

Forthcoming commits use having a payload argument added to
i2400m_schedule_work(), which then becomes nearly identical to
i2400m_queue_work().

This patch thus cleans up both's implementation, making it share
common helpers and adding the payload argument to
i2400m_schedule_work().

Subject: wimax/i2400m: add reason argument to i2400m_dev_reset_handle()

In preparation for reset_resume support, in which the same code path
is going to be used, add a diagnostic message to dev_reset_handle()
that can be used to distinguish how the device got there.

This uses the new payload argument added to i2400m_schedule_work() by
the previous commit.

Subject: wimax/i2400m: cache firmware on system suspend

In preparation for a reset_resume implementation, have the firmware
image be cached in memory when the system goes to suspend and released
when out.

This is needed in case the device resets during suspend; the driver
can't load firmware until resume is completed or bad deadlocks
happen.

The modus operandi for this was copied from the Orinoco USB driver.

The caching is done with a kobject to avoid race conditions when
releasing it. The fw loader path is altered only to first check for a
cached image before trying to load from disk. A Power Management event
notifier is register to call i2400m_fw_cache() or i2400m_fw_uncache()
which take care of the actual cache management.

Subject: wimax/i2400m: implement .reset_resume in USB subdriver

Current driver didn't implement the .reset_resume method. The i2400m
normally always reset on a comeback from system standby/hibernation.

This requires previously applied commits to cache the firmware image
file.

Subject: wimax/i2400m: don't overwrite error codes when failing to load
 firmware

Make sure that i2400m_dev_bootstrap() doesn't overwrite the last known
error code with -ENOENT; when a firmware fails to load, we want to
know the cause and not a generic error code.

Subject: wimax/i2400m: on device stop, clean up pending wake & TX work

When the i2400m device needs to wake up an idle WiMAX connection, it
schedules a workqueue job to do it.

Currently, only when the network stack called the _stop() method this
work struct was being cancelled. This has to be done every time the
device is stopped.

So add a call in i2400m_dev_stop() to take care of such cleanup, which
is now wrapped in i2400m_net_wake_stop().

Subject: wimax/i2400m: cleanup initialization/destruction flow

Currently the i2400m driver was starting in a weird way: registering a
network device, setting the device up and then registering a WiMAX
device.

This is an historic artifact, and was causing issues, a some early
reports the device sends were getting lost by issue of the wimax_dev
not being registered.

Fix said situation by doing the wimax device registration in
i2400m_setup() after network device registration and before starting
thed device.

As well, removed spurious setting of the state to UNINITIALIZED;
i2400m.dev_start() does that already.

Subject: wimax/i2400m: clarify and fix i2400m->{ready,updown}

The i2400m driver uses two different bits to distinguish how much the
driver is up. i2400m->ready is used to denote that the infrastructure
to communicate with the device is up and running. i2400m->updown is
used to indicate if 'ready' and the device is up and running, ready to
take control and data traffic.

However, all this was pretty dirty and not clear, with many open spots
where race conditions were present.

This commit cleans up the situation by:

 - documenting the usage of both bits

 - setting them only in specific, well controlled places
   (i2400m_dev_start, i2400m_dev_stop)

 - ensuring the i2400m workqueue can't get in the middle of the
   setting by flushing it when i2400m->ready is set to zero. This
   allows the report hook not having to check again for the bit to be
   set [rx.c:i2400m_report_hook_work()].

 - using i2400m->updown to determine if the device is up and running
   instead of the wimax state in i2400m_dev_reset_handle().

 - not loosing missed messages sent by the hardware before
   i2400m->ready is set. In rx.c, whatever the device sends can be
   sent to user space over the message pipes as soon as the wimax
   device is registered, so don't wait for i2400m->ready to be set.

From 0856ccf29dfbaf957e4be80dd3eb88d97810b633 Mon Sep 17 00:00:00 2001
From: Inaky Perez-Gonzalez <inaky@linux.intel.com>
Date: Wed, 16 Sep 2009 18:23:27 -0700
Subject: wimax/i2400m: introduce i2400m->bus_setup/release

The SDIO subdriver of the i2400m requires certain steps to be done
before we do any acces to the device, even for doing firmware upload.

This lead to a few ugly hacks, which basically involve doing those
steps in probe() before calling i2400m_setup() and undoing them in
disconnect() after claling i2400m_release(); but then, much of those
steps have to be repeated when resetting the device, suspending, etc
(in upcoming pre/post reset support).

Thus, a new pair of optional, bus-specific calls
i2400m->bus_{setup/release} are introduced. These are used to setup
basic infrastructure needed to load firmware onto the device.

This commit also updates the SDIO subdriver to use said calls.

Subject: wimax/i2400m: do bootmode buffer management in i2400m_setup/release()

After the introduction of i2400m->bus_setup/release, there is no more
race condition where the bootmode buffers are needed before
i2400m_setup() is called.

Before, the SDIO driver would setup RX before calling i2400m_setup()
and thus need those buffers; now RX setup is done in
i2400m->bus_setup(), which is called by i2400m_setup().

Thus, all the bootmode buffer management can now be done completely
inside i2400m_setup()/i2400m_release(), removing complexity from the
bus-specific drivers.

Subject: wimax/i2400m: Implement pre/post reset support in the USB driver

The USB stack can callback a driver is about to be reset by an
external entity and right after it, so the driver can save state and
then restore it.

This commit implements said support; it is implemented actually in the
core, bus-generic driver [i2400m_{pre,post}_reset()] and used by the
bus-specific drivers. This way the SDIO driver can also use it once
said support is brought to the SDIO stack.

Subject: wimax/i2400m: fix race condition with tcpdump et al

tcpdump and friends were not being able to decode packets sent via
WiMAX; they had a zero ethernet type, even when the stack was properly
sending them to the device with the right type.

It happens that the driver was overwriting the (fake) ethernet header
for creating the hardware header and that was bitting the cloning used
by tcpdump (et al) to look into the packets.

Use pkskb_expand_head() [method copied from the e1000 driver] to fix.

Thanks to Herbert Xu and Andi Kleen for helping to diagnose and
pointing to the right fix.

Subject: wimax/i2400m: use JUMP cmd for last FW chunk indication

Both secure and non-secure boot must set the JUMP command in the
bootmode header as the last FW chunk, so we change to use the JUMP
command to decide if the FW chunk download is completed.

Since we tend to use one single FW to support both secure and non-secure
boot for most of the time, I2400M_BRH_SIGNED_JUMP is actually found
even for non-secure boot. But in case the FW does come with
I2400M_BRH_JUMP, we check for both of them in i2400m_dnload_bcf().

Subject: wimax/i2400m: change the bcf_len to exclude the extended header size

The actual fw->size may not equal to the bcf size indicated in
the bcf header if the extended bcf debug header is added in the tail.

To reflect the actual fw size that will be downloaded to the device,
it is now retrived from from the size field indicated in the bcf header.

All of the headers (if there are extended headers) should indicate same
value for the size field since only one set of firmware chunks is downloaded

Subject: wimax/i2400m: when stopping the device, cancel any pending message

The stop procedure for the device must make sure that any task that is
waiting on a message is properly cancelled.

This was being taken care of only by the __i2400m_dev_reset_handle()
path and the rest was working by chance because the waits have a
timeout.

Fixed by adding a proper cancellation in __i2400m_dev_stop().

Subject: wimax/i2400m: fix deadlock: don't do BUS reset under
 i2400m->init_mutex

Since the addition of the pre/post reset handlers, it became clear
that we cannot do a I2400M-RT-BUS type reset while holding the
init_mutex, as in the case of USB, it will deadlock when trying to
call i2400m_pre_reset().

Thus, the following changes:

 - clarify the fact that calling bus_reset() w/ I2400M_RT_BUS while
   holding init_mutex is a no-no.

 - i2400m_dev_reset_handle() will do a BUS reset to recover a gone
   device after unlocking init_mutex.

 - in the USB reset implementation, when cold and warm reset fails,
   fallback to QUEUING a usb reset, not executing a USB reset, so it
   happens from another context and does not deadlock.

Upcoming changes will have to add things to this function that expose
more internals, which would mean more forward declarators.

Frankly, it doesn't need to be an inline, so moved to driver.c, where
the declarations will be taken from the header file.

Subject: wimax/i2400m: queue device's report until the driver is ready for
 them

The i2400m might start sending reports to the driver before it is done
setting up all the infrastructure needed for handling them.

Currently we were just dropping them when the driver wasn't ready and
that is bad in certain situations, as the sync between the driver's
idea of the device's state and the device's state dissapears.

This changes that by implementing a queue for handling
reports. Incoming reports are appended to it and a workstruct is woken
to process the list of queued reports.

When the device is not yet ready to handle them, the workstruct is not
woken, but at soon as the device becomes ready again, the queue is
processed.

As a consequence of this, i2400m_queue_work() is no longer used, and
thus removed.

Subject: wimax/i2400m: fix oops in TX when tearing down the device

All the entry points into the TX module should check if the device has
been torn down. Otherwise, when the device resets or shuts down, there
are windows when a call to i2400m_tx*() will oops the system.

For that, make i2400m_tx_release() set i2400m->tx_buf to NULL under
the tx_lock. Then, any entry point [i2400m_tx(), _tx_msg_sent(),
_tx_msg_get()] will check for i2400m->tx_buf to be NULL and exit
gracefully.

Subject: wimax/i2400m: Let device's status reports change the device state

Currently __i2400m_dev_start was forcing, after uploading firmware and
doing a few checks to WIMAX_ST_UNINITIALIZED.

This can be overriding state changes that the device might have caused
by sending reports; thus it makes more sense to remove it and let the
device update the status on its own by sending reports.

Subject: wimax/i2400m: fix oops caused by race condition when exiting USB
 kthreads

Current i2400m USB code had to threads (one for processing RX, one for
TX). When calling i2400m_{tx,rx}_release(), it would crash if the
thread had exited already due to an error.

So changed the code to have the thread fill in/out
i2400mu->{tx,rx}_kthread under a spinlock; then the _release()
function will call kthread_stop() only if {rx,tx}_kthread is still
set.

Subject: wimax/i2400m: make i2400m->bus_dev_{stop,start}() optional

In coming commits, the i2400m SDIO driver will not use
i2400m->bus_dev_stop().

Thus changed to check before calling, as an empty stub has more
overhead than a call to check if the function pointer is non-NULL.

Subject: wimax/i2400m: SDIO: fix oops on reset when TXing on uninitialized
 data

Currently the SDIO part of the TX resources were initialized/released
with bus_dev_{start,stop}.

The generic code's TX subsystem is destroyed afterwards, so there is a
window from the bus-TX destruction to the generic-TX destruction where
the generic-TX code might call into bus-TX to do transactions.

The SDIO code cannot really cope with this (whereas in USB, how it is
laid out, it correctly ignores it). In any case, it made no sense for
the SDIO TX code to be in i2400m->bus_dev_start/stop(), so moved to
i2400m->bus_setup/release(), which also takes care of the oops.

Change RX large buffer size based on MTU. If pages are larger
than the MTU the page is divided up into multiple chunks and passed to
the hardware.  When pages are smaller than MTU each RX buffer can
contain be comprised of up to 2 pages.

From ab69a5ae2bdc0b5e20e935a7b75f30aa3f4c3bae Mon Sep 17 00:00:00 2001
From: Tomas Winkler <tomas.winkler@intel.com>
Date: Sat, 17 Oct 2009 09:09:34 +0000
Subject: iwmc3200top: Add Intel Wireless MultiCom 3200 top driver.

This patch adds Intel Wireless MultiCom 3200 top driver.
IWMC3200 is 4Wireless Com CHIP (GPS/BT/WiFi/WiMAX).
Top driver is responsible for device initialization and firmware download.
Firmware handled by top is responsible for top itself and
as well as bluetooth and GPS coms. (Wifi and WiMax provide their own firmware)
In addition top driver is used to retrieve firmware logs
and supports other debugging features

Subject: can: provide library functions for skb allocation

This patch makes the private functions alloc_can_skb() and
alloc_can_err_skb() of the at91_can driver public and adapts all
drivers to use these. While making the patch I realized, that
the skb's are *not* setup consistently. It's now done as shown
below:

  skb->protocol = htons(ETH_P_CAN);
  skb->pkt_type = PACKET_BROADCAST;
  skb->ip_summed = CHECKSUM_UNNECESSARY;
  *cf = (struct can_frame *)skb_put(skb, sizeof(struct can_frame));
  memset(*cf, 0, sizeof(struct can_frame));

The frame is zeroed out to avoid uninitialized data to be passed to
user space. Some drivers or library code did not set "pkt_type" or
"ip_summed". Also,  "__constant_htons()" should not be used for
runtime invocations, as pointed out by David Miller.

Subject: sfc: 10Xpress: Report support for pause frames

Commits 27fbc7d 'mdio: Expose pause frame advertising flags to ethtool'
and c634263 'sfc: 10Xpress: Initialise pause advertising flags'
added to our reported advertising flags.

efx_mdio_set_settings() requires that all advertising flags are
also present in the supported flags, so make sure that is true.

- * Support for the SFE4001 and SFN4111T NICs.

- * The SFE4001 does not power-up fully at reset due to its high power
- * consumption.  We control its power via a PCA9539 I/O expander.
- * Both boards have a MAX6647 temperature monitor which we expose to
- * the lm90 driver.
- *
- * This also provides minimal support for reflashing the PHY, which is
- * initiated by resetting it with the FLASH_CFG_1 pin pulled down.
- * On SFE4001 rev A2 and later this is connected to the 3V3X output of
- * the IO-expander; on the SFN4111T it is connected to Falcon's GPIO3.
- * We represent reflash mode as PHY_MODE_SPECIAL and make it mutually
- * exclusive with the network device being open.

From 56241ceb9e75fc1a5fb142a754096ad6c6ab19ee Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Fri, 23 Oct 2009 08:30:06 +0000
Subject: sfc: Remove versioned bitfield macros

These macros are not extensible to more than two NIC types without
repetition of register definitions, and they are only used to deal
with a few fields in RX_CFG_REG and global events which moved between
Falcon rev A1 and B0.

Therefore:
- Move RX_CFG_REG initialisation into its own function which tests the
  NIC revision just once
- Explicitly test the NIC revision when checking the RX_RECOVERY flag in
  global events
- Merge definitions of RX_XOFF_MAC_EN flag, which did not move
- Remove the macro definitions

Subject: sfc: Update hardware definitions for Siena

Siena is still based on the Falcon hardware architecture and will
share many of these definitions, so replace falcon_hwdefs.h with
regs.h.

The new definitions have been generated according to a naming
convention which incorporates the type and revision information.
Update the code accordingly.

From 12d00cadcc45382fc127712aa35bd0c96cbf81d9 Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Fri, 23 Oct 2009 08:30:46 +0000
Subject: sfc: Rename register I/O header and functions used by both Falcon and
 Siena

While we're at it, use type suffixes of 'd', 'q' and 'o', consistent
with register type names.

- * Falcon hardware access
- *
- **************************************************************************
- *
- * Notes on locking strategy:
- *
- * Most Falcon registers require 16-byte (or 8-byte, for SRAM
- * registers) atomic writes which necessitates locking.
- * Under normal operation few writes to the Falcon BAR are made and these
- * registers (EVQ_RPTR_REG, RX_DESC_UPD_REG and TX_DESC_UPD_REG) are special
- * cased to allow 4-byte (hence lockless) accesses.
- *
- * It *is* safe to write to these 4-byte registers in the middle of an
- * access to an 8-byte or 16-byte register.  We therefore use a
- * spinlock to protect accesses to the larger registers, but no locks
- * for the 4-byte registers.
- *
- * A write barrier is needed to ensure that DW3 is written after DW0/1/2
- * due to the way the 16byte registers are "collected" in the Falcon BIU
- *
- * We also lock when carrying out reads, to ensure consistency of the
- * data (made possible since the BIU reads all 128 bits into a cache).
- * Reads are very rare, so this isn't a significant performance
- * impact.  (Most data transferred from NIC to host is DMAed directly
- * into host memory).
- *
- * I/O BAR access uses locks for both reads and writes (but is only provided
- * for testing purposes).

+ *
+ * NIC register I/O
+ *
+ **************************************************************************
+ *
+ * Notes on locking strategy:
+ *
+ * Most NIC registers require 16-byte (or 8-byte, for SRAM) atomic writes
+ * which necessitates locking.
+ * Under normal operation few writes to NIC registers are made and these
+ * registers (EVQ_RPTR_REG, RX_DESC_UPD_REG and TX_DESC_UPD_REG) are special
+ * cased to allow 4-byte (hence lockless) accesses.
+ *
+ * It *is* safe to write to these 4-byte registers in the middle of an
+ * access to an 8-byte or 16-byte register.  We therefore use a
+ * spinlock to protect accesses to the larger registers, but no locks
+ * for the 4-byte registers.
+ *
+ * A write barrier is needed to ensure that DW3 is written after DW0/1/2
+ * due to the way the 16byte registers are "collected" in the BIU.
+ *
+ * We also lock when carrying out reads, to ensure consistency of the
+ * data (made possible since the BIU reads all 128 bits into a cache).
+ * Reads are very rare, so this isn't a significant performance
+ * impact.  (Most data transferred from NIC to host is DMAed directly
+ * into host memory).
+ *
+ * I/O BAR access uses locks for both reads and writes (but is only provided
+ * for testing purposes).

Subject: sfc: Move all TX DMA length limiting into tx.c

Replace the duplicated logic in efx_enqueue_skb() and
efx_tx_queue_insert() with an inline function, efx_max_tx_len().

Remove the failed attempt at abstracting hardware-specifics and put
all the magic numbers in efx_max_tx_len().

Subject: sfc: Move MTD probe after netdev registration and name allocation

The MTD partition is named based on the netdev name, which is set to
'eth%d' before registration.  Also, the MTD partition will currently
be left registered if netdev registration fails.

Fix both these problems by moving the MTD probe after netdev
registration.  Hold the RTNL to serialise this with the netdev
notifier that calls efx_mtd_rename().

Subject: sfc: Rename 'xfp' file and functions to reflect reality

The 'XFP' driver is really a driver for the QT2022C2 and QT2025C PHYs,
covering both more and less than XFP.  Rename its functions and
constants to reflect reality and to reduce namespace pollution when
sfc is a built-in driver.

Now that the bonding device is no longer used in determining the device to
which to send packets, it can be dropped from the argument list of the various

The qual element in ieee80211_rx_status is not used anymore, so we don't need
to set it in the wl1271_rx_status() function.  This saves a bit of time in
the RX path.

Subject: wl1271: Implementation for SPI busy word checking

This patch adds implementation for checking for SPI busy words - i.e.
honoring a delay request from the WLAN chipset upon reading
registers/memory.

To optimized the average SPI ready by 32 bits, also configure the number
of busywords to one to disable the "fixed-busy-word" functionality.

Subject: wl1271: Use vmalloc to allocate memory for firmware

Use vmalloc to allocate memory for the firmware image, and use a smaller
linear buffer for the actual transfer of the firmware to the chipset.

This patch is an adaptation of a similar patch for wl1251 by Kalle Valo.

Subject: iwl3945: update iwl3945_apm_init()

Update iwl3945_apm_init() to set up device registers in sequence most recently
recommended by factory.

Add resets for APMG interrupts and radio chip, formerly done only in
iwl3945_apm_reset(); moving them here assures that apm_init() will do
a complete job of preparing hardware not only after platform boot,
but also after apm_stop() has executed (due to rfkill, ifconfig down,
driver unload, etc.).  This is in preparation to completely remove apm_reset().

Add some comments.

Subject: iwlwifi: turn off device when not used.

In some cases (e.g. when mac80211 calls iwl_mac_stop() for suspend or user
no longer wants device active), device has not been going into low power state
via __iwl_down().  apm_ops.reset() does not put device into low power state;
instead it resets the device, then puts it into a powered-up state ready to be
re-loaded with uCode and re-started.  This has needlessly warmed up user's
laptops and drained batteries.

With current architecture in which mac80211 controls device up/down (including
resetting device after firmware errors), there is no need for apm_ops.reset()
any more; apm_ops.reset() is basically a combination of apm_ops.stop() and
apm_ops.init().

Instead, __iwl_down() now unconditionally places the device into a low-power
state via apm_ops.stop(). Device may be re-started via __iwl_up() calling
apm_ops.init() as soon as it may be needed (e.g. quickly for firmware errors),
but in the meantime, device will stop wasting energy.

Note that, even in this low power state, if driver re-enables interrupts,
the device retains the ability to sense the hardware RF-KILL switch, and
(except for 3945) interrupt the host when it changes.

Subject: iwl3945: remove unnecessary call to apm_ops.reset()

Now that we're unconditionally using apm_ops.stop() to reset and power-down
the device in __iwl3945_down(), the apm_ops.reset() is redundant.  Removing
this call will also allow us to remove iwl3945_apm_reset().

Remove unneeded iwl_clear_bit(CSR_GP_CNTRL_REG_FLAG_MAC_ACCESS_REQ) because
this bit will be set again very soon in iwl3945_hw_txq_ctx_stop() and other
following calls.

Subject: iwlwifi: additional items in sensitivity range table

Add more items to sensitivity range table to avoid using hardcoded values.
Initialize the table per device since unique per device information is
required to perform sensitivity calibration.

additional items in sensitivity range table:
   .barker_corr_th_min: Barker correlation threshold minimum
   .barker_corr_th_min_mrc: Barker correlation threshold minimum for MRC
   .nrg_th_cca: Energy threshold for Clear Channel Assessment

Barker codes are a technique used in WLAN encoding for transmission.
MRC is "Maximal Ratio Combining", a technique for optimally combining the
signals from 2 or more receivers to achieve a better signal.

Subject: iwlwifi: fix userspace setting of sleep_level_override

The sleep_level_override debugfs file is used by the user to request a
static power index instead of the dynamic sleep values. Users are expected
to provide value from 1 to 5 as an index or -1 to disable it.

The problem at the moment is that users can also provide 0 to this file
which, together with the value 1, is translated to index 1. This is
confusing and even more so when users write 0 to sleep_level_override and
then read 1 from it afterwards.

Modify checking to treat 0 as invalid.

Call wiphy_rfkill_set_hw_state() only when RFKILL switch changes.
Add IWL_DEBUG_RF_KILL log message and documentation.

Subject: iwl3945: move iwl_power_initialize()

iwl_power_initialize() initializes driver data (not device hardware), and does
not need to execute more than once (when the driver initializes).  Therefore, it
does not belong in iwl3945_apm_init(), which initializes hardware, and may run
more than once.

Move it to iwl3945_pci_probe(), where it will run only once.  This agrees
with similar placement in iwl-agn.c's iwl_pci_probe(), although placement
under "services" seemed more appropriate than under "mac80211".

Subject: iwlwifi: showing accumulative ucode statistics counters

Adding accumulative statistics counters in iwlwifi driver.
Statistics counters are reported by uCode every beacon interval; but can
be reset by uCode when needed. The accumulative statistics counters is
maintained by driver to keep track of the history of all the counters.

Update the ucode stats files in debugfs to display both latest and
accumulative counters.

Subject: iwlwifi/iwl3945: unify rts_tx_cmd_flag

3945 and 4965 share the functionality for setting RTS and CTS to
the tx_cmd. Unify these functions and move the common
functionality to core.

Subject: iwlwifi: update channel switch command API

Channel switch host command has different data structure for
different devices. Adding additional structures to support 5000 and 6000
NICs. unlike 4965, starting with 5000 series, the tx power is managed by
uCode, there is no tx power db information need to be passing from driver to
uCode; but the space needs to be reserved to match uCode expection.

1000 NIC do not support channel switch operation since it is 'bgn'
device, there is no need to have data structure defined for it.

Subject: wl1271: workaround to send a disconnect before rejoining

We don't get any indication from the stack when we have disassociated.  In
wl1271, it is important to send a CMD_DISCONNECT before joining again,
because the firmware cleans some things up.  So we check if we're already
joined and disconnect if that's the case.

Subject: wl1271: add workaround to avoid distortion due to excessive tx power

We still don't have proper calibration for our devices, so we are using way
too much power for TX, which causes a lot of distortion.  This hack hardcodes
the txpower to 7dBm.

Subject: wl1271: Remove outdated SPI functions

With the change to the new firmware, there was a change to firmware memory
partitioning. Along with that change, the translation of all partitions was
unified, and separate functions for reg and mem access became unnecessary.

Cleanup the unnecessary functions.

We shouldn't use a join command to change the filter settings while
associated.  The right way to do it is to use ACX_RX_CFG.

Subject: wl1271: remove unnecessary joins and join only when the bssid changes

We were using the join command to change some settings when the stack asked
us to do it.  In many cases they were not needed (and could cause potential
problems), so they were removed.  In other cases there are ACX commands that
can be used instead of using join to reconfigure.

Subject: iwlwifi: use paged Rx

This switches the iwlwifi driver to use paged skb from linear skb for Rx
buffer. So that it relieves some Rx buffer allocation pressure for the
memory subsystem. Currently iwlwifi (4K for 3945) requests 8K bytes for
Rx buffer. Due to the trailing skb_shared_info in the skb->data,
alloc_skb() will do the next order allocation, which is 16K bytes. This
is suboptimal and more likely to fail when the system is under memory
usage pressure. Switching to paged Rx skb lets us allocate the RXB
directly by alloc_pages(), so that only order 1 allocation is required.

It also adjusts the area spin_lock (with IRQ disabled) protected in the
tasklet because tasklet guarentees to run only on one CPU and the new
unprotected code can be preempted by the IRQ handler. This saves us from
spawning another workqueue to make skb_linearize/__pskb_pull_tail happy
(which cannot be called in hard irq context).

Finally, mac80211 doesn't support paged Rx yet. So we linearize the skb
for all the management frames and software decryption or defragmentation
required data frames before handed to mac80211. For all the other frames,
we __pskb_pull_tail 64 bytes in the linear area of the skb for mac80211
to handle them properly.

Subject: wl1271: Workaround for reference clock setting on boot.

If the 38.4MHz reference clock is configured to the firmware, it crashes
on boot. Configuring an experimental 38.4MHz in XTAL mode allows the
firmware to boot, and everything appears to work.

Subject: wl1271: Add structure for firmware configuration values

In order to make the firmware configuration more manageable, collect
hardcoded configuration values into one data structure, and set default values
there.

Add the SoftGemini BT/WLAN coex paramters into the config structure.

initialization was tried again without reboot.

Subject: wl1271: Support for IPv4 ARP filtering
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add support for IPv4 ARP filtering in the driver. This will dramatically
reduce the number of unnecessary interrupts by the device in conqested
networks.

This patch is based on a similar patch to wl1251 by Janne Ylälehto.

Several memory allocation related failure cases were not properly
handled by the driver - the result was that in low memory conditions
booting of a corrupted FW could be attempted - and user space would not
get proper failure code.

We cannot be in PS mode when running PLT tests, so we need to make sure we're
in active mode.  Also, we need to clear up the rx_counter when we stop PLT,

Subject: wl1251: rename spi device to wl1251

During rename of the driver from wl12xx to wl1251 the spi device name
was accidentally left as wl12xx. Rename it to wl1251 which is the proper
name of the driver.

Subject: ath5k: use noise calibration from madwifi hal

This updates ath5k to calibrate the noise floor similar to the
way it is done in the madwifi hal and ath9k.  Of note:

- we start NF measurement at the same time as AGC calibration,
  but do not actually read the value until the periodic (long)
  calibration
- we keep a history of the last few values read and write the
  median back to the hardware for CCA
- we do not complain if NF calibration isn't complete, instead
  we keep the last read value.

Subject: wl1271: fix endianess issues

We were not handling endianess correctly.  The wl1271 chip runs on
little-endian values.  This patch makes sure that all the communication with
the wl1271 firmware is done in little-endian by using cpu_to_le* and
le*_to_cpu where appropriate.

Also, all the struct definitions for data exchanged with the firmware has
been changed to use __le16/32 types instead of u16/32.

This fixes a few sparse warnings, such as these:

Subject: wl1251: use ieee80211_rx_ni()

Because of SPI and SDIO wl1251 does everything in a workqueue, including
calling ieee80211_rx() which should be called with bottom halves disabled.
An error message is emitted because of this:

NOHZ: local_softirq_pending 08

Fix this by using ieee80211_rx_ni().

Subject: iwmc3200wifi: CT kill support

We set the initial CT (Temperature control) value to 110 degrees.
If the chip goes over that threshold, we hard block the device which will turn
it down. At the same time we schedule a 30 seconds delayed work that unblock
the device (and userspace is supposed to bring it back up), hoping that the
chip will have cooled down by then...

Subject: iwmc3200wifi: Profile flags can be WPA1 or WPA2 not both

UMAC will ASSERT if the profile security flag is WPA1 | WPA2, so we can only
accept one of those.
Moreover wpa_s wext and nl80211 drivers dont try to send WPA1 | WPA2, but only
one at a time.

Subject: iwmc3200wifi: SDIO disable race fix

When calling sdio->bus_disable(), we are flushing the command lists before
disabling the sdio function. We can thus potentially get a command response
after having flushed the command list.
To avoid that race, we have to call iwm_reset() after disabling the sdio
function.

Subject: iwmc3200wifi: Check for cmd pointer before dereferencing it

The wifi_if_wrapper notification handling code uses a cmd pointer without
checking if it's valid or not. We're dereferencing it because we assume that
we only get to that point if there was a pending command for us. That's not
always true, so we'd better check.

Subject: iwlwifi: show current power save status reported by uCode

Power save request is sent from driver to uCode, but there is no
indication from uCode about the current device power save state.

Reading GP_CNTRL register bit 25:24 to show the current power save
status

00: no power save
01: MAC power down
10: PHY power down
11: Error

The uCode could switch in and out of power save mode in the order of
once per 100-300 ms in many cases. The reading here should just be used for
reference on the current uCode power save status. Do not confuse this
reading with the PowerSave set by driver and mac80211.

Subject: iwlagn: store station rate scale information in mac80211 station
 structure

Currently mac80211 initializes the rate scaling before notifying the driver
of the station's existence. The driver dealt with this by not relying on
mac80211's station notifications and instead mixing this functionality with
the rate scaling code and other places. To clean this up the driver needs
to do rate scaling initialization after being notified of the station, this
can be done if the rate scaling information forms part of the station
information passed from mac80211 to driver.

Subject: iwlwifi: rework for static power save

For static power save, the actual intervals are calculated by driver based on
the default table and DTIM flag, then sent to uCode when the scheme
is changed.

Three tables are defined based on DTIM period.
	1. DTIM 0 - 2
	2. DTIM 3 - 10
	3. DTIM > 11

The actual number of DTIM a station may miss may not exceed the
following:
	. Only 1 DTIM may be skipped at PI=4 when allowed
	. Only 2 DTIMs may be skipped at PI=5 when allowed
	. DTIM may be skipped only 5 sec after last activity
	. DTIM may be skipped only 30 sec after connection establishment

Only allow user to override the power_level when rf is ready to make sure
power level gets changed upon request.

Subject: wl1271: use ieee80211_rx_ni()

Use the new ieee80211_rx_ni() function instead of ieee80211_rx().  Since we
use a workqueue to handle the RX path, we need to call the new function,
which disables bottom half handling.  This patch fixes the NOHZ:
local_softirq_pending messages.

Subject: zd1211rw: Fix TX status reporting in order to have proper rate
 control

First, we reduce the number of hardware retries to 0 (ie 2 real retries
for each rate). Next, when we report the retries to mac80211, we always
report a retry count of 1 (it seems to be 2 in fact, but using 2 seems
to lead to wrong performance for some reason). We use a state machine to
determine the real fate of a packet based on the 802.11 ACK and what the
Zydas hardware is saying when a real retry occurs. The real retry rates
are encoded in a static array. It has been tested with both zd1211 and
zd1211b hardware. Of course, since the Zydas hardware is not reporting
retries accurately, we are just doing our best in order to get the best
performance (ie higher throughput).

From d37b4fdd43f7e5686c40181f33a50a7ee03ddbd8 Mon Sep 17 00:00:00 2001
From: Holger Schurig <hs4233@mail.mn-solutions.de>

Subject: libertas: remove unused 11d code

Most of the 11d code was protected with an "if (priv->enable11d)" clause.
But there was no code that anywhere that was able to set this
variable to true. So all 11d code was dead for almost a year and no one
complained. That's enought incentive to remove this code.

Besides removing old cruft, we gain back the 11d capability in a common way
when we merge the cfg80211 functionality.

From 2d46502dce3c79c3c15ac537cb271911f58d12d1 Mon Sep 17 00:00:00 2001
From: Holger Schurig <hs4233@mail.mn-solutions.de>
Date: Thu, 22 Oct 2009 15:30:48 +0200
Subject: libertas: move scan/assoc related stuff

Another cfg80211-preparation patch: removes some code/definitions from
main.c and dev.h and put's it into assoc.c/.h, scan.c/.h.

No function change.

Subject: libertas: remove some references to IW_MODE_abc

... in pursue to quaff the wide-spread references to WEXT constants.

When setting SNMP_MIB_OID_BSS_TYPE, wext.c can directly calculate the value
the firmware wants.

Reading of SNMP_MIB_OID_BSS_TYPE doesn't happen anywhere, so no need to
convert the firmware value into WEXT values anyway.

In Rx gain balancing (chain noise) computation for 5000 series and up,
the delta gain calculation should use the average noise of default
chain, not "chain 0" which do not exist for all the devices.

Subject: iwlwifi: consolidate apm_init() functions

Consolidate most iwlXXXX_apm_init() functions into single iwl_apm_init().
Keep iwl3945_apm_init(), but leverage iwl_apm_init() for most functionality.
Update 4965 init sequence to follow most recent factory recommendations.

Add following members to struct iwl_cfg to guide the init sequence:
pll_cfg_val (replaces needs_pll_cfg), set_l0s, use_bsm

Move L0S enable/disable from nic_config() functions to iwl_apm_init().
This satisifies the "FIXME: put here L1A -L0S w/a" notice, and complies
with factory-recommended sequence.

Add debug info message in iwl_apm_init(), and symmetrical message
in iwl_apm_stop().

Subject: iwlwifi: separate led function from statistic notification

Detach led background task from statistic notification routine. if led
blinking is required; the blink rate is based on the traffic condition.
It do not relate to statistics notification. In addition to that, there is
not a requirement for statistics notification has to occur all the time.

Subject: iwlwifi: fix use after free bug for paged rx

In the paged rx patch (4854fde2), I introduced a bug that could possibly
touch an already freed page. It is fixed by avoiding the access in this
patch. I've also added some comments so that other people touching the
code won't make the same mistake. In the future, if we cannot avoid
access the page after being handled to the upper layer, we can use
get_page/put_page to handle it. For now, it's just not necessary.

It also fixed a debug message print bug reported by Stanislaw Gruszka
<sgruszka@redhat.com>.

Subject: iwlwifi: add channel switch support to 5000 series and up

Support "channel switch" request by issue "channel switch" host command
to uCode.

There is no separated "channel switch" indication from mac80211,
when detected "IEEE80211_CONF_CHANGE_CHANNEL" flag in iwl_mac_config(),
if the station is in "associated" state, then assume "channel switch
announcement" IE was received by mac80211.

For notification packets and SKBs that fail to rx correctly, add
them back into the rx_free list so that the pages can be reused
later. This avoids allocating new rx pages unnecessarily.

For 6x00 and 6x50 series devices, APIv4 is the lowest firmware version
driver can support. This is also the lowest API version available to the
public so there is no need for backward compatibility support for the
earlier API versions.

Subject: iwlwifi: make sure device is reset when unloading driver

Add unconditional call to apm_ops.stop() to reset device to low power state
when unloading driver.  Some paths have existed to unload driver *without*
resetting device, therefore some errors have persisted through multiple
load/unload cycles, until the whole platform gets rebooted; this is an
attempt to remedy some of those situations.  Sorry, I can't seem to find
a bughost.org bug that specifically has these symptoms, but I had it happen
recently here.

Note that this will *not* fix situations in which the PCI express bus has
crashed (evidenced by register reads showing "0xffffffff"), e.g. bughost.org
1855 and 2096; device is unreachable from driver in those cases.

Subject: igb: add new data structure for handling interrupts and NAPI

Add a new igb_q_vector data structure to handle interrupts and NAPI.  This
helps to abstract the rings away from the adapter struct.  In addition it
allows for a bit of consolidation since a tx and rx ring can share a
q_vector.

Subject: igb: remove rx checksum good counter

Counting packets with a good checksum can cause a significant amount of cache
line bouncing due to the shared counter being written to by all of the queues.
In order to avoid this I am removing the counter since we still have the
checksum failed counter which will tell us if there are any issues.

Subject: igb: increase minimum rx buffer size to 1K

This update increases the minimum rx buffer size to 1K.  The reason for this
change is to support SR-IOV and avoid any conflicts with the rings being able
to set their own MTU sizes.

Subject: igb: remove rx_ps_hdr_len

This patch removes the rx_ps_hdr_len which isn't really needed since we can
now use rx_buffer_len less than 1K to indicate that we are in a packet split
mode.  We also don't need it since we always use a half page for the data
buffers when receiving so we always know the size to map/unmap.

Subject: igb: move SRRCTL register configuration into ring specific config

The SRRCTL register exists per ring.  Instead of configuring all of them in
the RCTL configuration which is meant to be global it makes more sense to move
this out into the ring specific configuration.

Subject: igb: change the head and tail offsets into pointers

Since we are writting to the head/tail pointers frequently we might as well
save ourselves some processing time by converting the head and tail offsets
directly to pointers.  This will shave a few cycles off the rx/tx path and
allows us to move one step closer to the rings being a bit more independant of
each other.

Subject: igb: move rx_buffer_len into the ring structure

This patch moves the rx_buffer_len value into the ring structure.  This allows
greater flexibility and the option of doing things such as supporting packet
split only on some queues, or enabling virtualization.

Subject: igb: move alloc_failed and csum_err stats into per rx-ring stat

The allocation failed and checksum error stats are currently kept as a
global stat.  If we end up allocating the queues to multiple netdevs then
the global counter doesn't make much sense.  For this reason I felt it
necessary to move the alloc_rx_buff_failed stat into the rx_stats
portion of the rx_ring.

Subject: igb: add a flags value to the ring

This patch adds a flags value to the ring that cleans up some of the last
remaining items from the ring in order to help seperate it from the adapter
struct.  By implementing these flags it becomes possible for different rings
to support different functions such as rx checksumming.

Subject: igb: place a pointer to the netdev struct in the ring itself

This change adds a pointer to the netdev to the ring itself.  The idea being
at some point in the future it will be possible to support multiple netdevs
from a single adapter struct.

Subject: igb: move the multiple receive queue configuration into seperate
 function

This patch moves the multiple receive queue configuration into a seperate
function from igb_configure_rx.  We can essentially do the configuration for
the multiple receive queues just prior to enabling the RX and this will allow
us to seperate the queue enablement from the receive queue layout
configuration.

Subject: igb: delay VF reset notification until after interrupts are enabed

This update delays the VF reset notification until after interrupts are
enabled.  Otherwise there is a chance of having the VF try to reset itself too
soon and being ignored by the PF as a result.

Subject: igb: re-use ring configuration code in ethtool testing

Since all of the ring code is now specific to the ring instead of the adapter
struct it is possible to cut a large section of code out of the ethtool
testing configuraiton since we can just use the existing functions to
configure the rings.

Subject: igb: make tx ring map and free functionality non-static

This change makes a minor change to the xmit_frame_ring_adv funcition in that
it moves 2 checks from it into the xmit_frame_adv since the checks were not
ring specific.  In addition it exports the xmit_frame_ring_adv and the
unmap_and_free_tx_resource calls so that they can be used by other code such
as the ethtool loopback testing calls.

Subject: igb: add single vector msi-x testing to interrupt test

This change adds testing of the first msix vector to the interrupt testing.
This should help with determining the cause of interrupt issues when they are
encountered.

Subject: sfc: Really allow RX checksum offload to be disabled

We have never checked the efx_nic::rx_checksum_enabled flag everywhere
we should, and since the switch to GRO we don't check it anywhere.
It's simplest to check it in the one place where we initialise the
per-packet checksummed flag.

Subject: igb: add support for seperate tx-usecs setting in ethtool

This patch adds support for a seperate tx-usecs interrupt moderation setting
in ethtool which is supported when tx and rx interrupt vectors are sperated.

Subject: igb: cleanup some of the code related to hw timestamping

The code for the hw timestamping is a bit bulky and making some of the
functions difficult to read.  In order to clean things up a bit I am moving
the timestamping operations into seperate functions.

From d249be54745259980dcbd898bdfeb7307c9c5e10 Mon Sep 17 00:00:00 2001

Subject: igb: use packet buffer sizes from RXPBS register

This patch changes the configuration for 82576 so that it uses the actual
value of the 82576 rx packet buffer size instead of just assuming the
value.

Subject: igb: rework use of VMOLR in regards to PF and VFs

This patch updates the use of the VMOLR to include enabling multicast
promiscous for the VFs should they attempt to send over 30 multicast
addresses or if they use the new message type to enable multicast
promiscuous.

Subject: igb: only process global stats in igb_update_stats

This patch moves the update of adapter->net_stats.rx/tx values out of the
interrupt routine and into igb_update_stats by just adding together the
tx/rx byte/packet counts for the rings.

This change moves global_quad_port_a into igb_probe as a static define
since it doesn't actually need to be global.

This patch changes a few things so that instead of firing a link status
interrupt directly the get_link_status bit is set and the watchdog is
scheduled.  In addition the mailbox bit is now only enabled if VFs are
enabled.

Subject: NET/KS8695: add support NAPI for Rx

Add support NAPI Rx API for KS8695NET driver.

v2, change the Rx function to NAPI.

in <KS8695X Integrated Multi-port Gateway Solution Register Description
 v1.0>:

Interrupt Enable Register (offset 0xE204)
Bit29 : WAN MAC Receive Interrupt Enable
Bit16 : LAN MAC Receive Interrupt Enable

Interrupt Status Register (Offset 0xF208)
Bit29: WAN MAC Receive Status
Bit16: LAN MAC Receive Status

see arch/arm/mach-ks8695/devices.c:
ks8695_wan_resources[] and ks8695_lan_resources[]
have IORESOURCE_IRQ , it have define the RX irq,
for wan, irq = 29; for lan ,irq = 16.
so we can do this read the interrupt status:

unsigned long mask_bit = 1 << ksp->rx_irq;
status = readl(KS8695_IRQ_VA + KS8695_INTST);

Subject: tc35815: Fix return value of tc35815_do_interrupt when NAPI enabled

Return received count correctly even if tx completed at the same time.
Currently NAPI is disabled for this driver so this patch does not fix
any real problem.

Subject: via-velocity: Remove private device list

via-velocity maintains a list of its devices in order to determine
whether a netdev notification applies to one of them.  That can be
determined simply by checking the netdev_ops pointer, so the list can
be removed.

Compile-tested only.

Subject: e100: Fix to allow systems with FW based cards to resume from STD

Devices with loadable firmware must have their firmware reloaded
after the system resumes from sleep, but the request_firmare()
API is not available at this point in the resume flow because
tasks are not yet running, and the system will hang if it is
called. Work around this issue by only calling request_firmware()
for a device's first firmware load, and cache a copy of the pointer
to the firmware blob for that device, so that we may reload firmware
images even during resume.

The 82599 EEPROM supports alternative prefix for World Wide Node Name
(WWNN) and World Wide Port Name (WWPN). The prefixes can be used together
with the SAN MAC address to form the WWNN and WWPN, which can be used by
upper layer drivers such as Fiber Channel over Ethernet (FCoE).

Subject: ixgbe: Add support for netdev_ops.ndo_fcoe_get_wwn to 82599

Implements the netdev_ops.ndo_fcoe_get_wwn in 82599 if it finds valid
prefix for the World Wide Node Name (WWNN) or World Wide Port Name (WWPN),
as well as valid SAN MAC address.

Subject: e1000e: flow control doesn't re-enable

When changing flow control (pause) parameters, the flow control thresholds
(i.e. when to send XON/XOFF frames) may not be setup correctly on parts
with copper media.  Call the existing e1000_set_fc_watermarks()
function to set these thresholds.

Subject: gigaset: fix format string typo in CAPI dial command

A missing dot lead to garbage characters being included in the
dial command generated from a CAPI CONNECT_REQ message, which
interestingly enough worked anyway, illustrating the resilience
of the device.

From: Tilman Schmidt <tilman@imap.cc>
Date: Sun, 25 Oct 2009 09:29:57 +0000
Subject: gigaset: fix bad assumptions about CAPI skbuffs

The CAPI interface incorrectly assumed that CAPI messages would always
start at the beginning of the data buffer: fix by treating DATA_B3
messages as the link layer header to their payload data. This fix
changes the way acknowledgement information is propagated through the
hardware specific modules and thereby impacts the ISDN4Linux variant
of the driver, too.

Also some assumptions about methods not being called from interrupt
context turned out to be unwarranted; fix by using dev_kfree_skb_any()
wherever non-interrupt context isn't guaranteed.

Subject: usb_gigaset: code cleanup

Reorganize the code of the Gigaset M10x driver to make it more
readable, less redundant, better aligned to the style of other
parts of the driver, and cause fewer checkpatch.pl complaints.

Impact: code reorganization, no functional change

Subject: gigaset: convert strcmp chain to table lookup

Replace the sequence of strcmp calls for interpreting ZSAU parameter
strings by a table of known strings and lookup loop to improve
readability.

Impact: readability improvement, no functional change

Subject: sfc: Feed GRO result into RX allocation policy and interrupt
 moderation

When GRO is successfully merging received packets, we should allocate
raw page buffers rather than skbs that will be discarded by GRO.
Otherwise, we should allocate skbs.

GRO also benefits from higher interrupt moderation, so increase the
score for mergeable RX packets.

(net: add a list_head parameter to dellink() method),
I forgot to actually use this parameter in veth_dellink.

I remember feeling a bit uncomfortable about veth_close(),
because it does :

netif_carrier_off(priv->peer);

Subject: bond: Simplify bond_create.

Stop calling dev_get_by_name to see if the bond device already
exists.  register_netdevice already does that.

Stop calling bond_deinit if register_netdevice fails as bond_uninit
is guaranteed to be called if bond_init succeeds.

Subject: bond: Simplify bond device destruction

Manually inline the code from bond_deinit to bond_uninit.  bond_uninit
is the only caller and it is short.

Move the call of bond_release_all from the netdev notifier into
bond_uninit.  The call site is effectively the same and performing
the call explicitly allows all the paths for destroying a
bonding device to behave the same way.

Subject: bond: Implement a basic set of rtnl link ops

This implements a basic set of rtnl link ops and takes advantage of
the fact that rtnl_link_unregister kills all of the surviving
devices to all us to kill bond_free_all.  A module alias
is added so ip link add can pull in the bonding module.

Subject: bond: Get the rtnl_link_ops support correct

- Don't call rtnl_link_unregister if rtnl_link_register fails
- Set .priv_size so we aren't stomping on uninitialized memory
  when we use netdev_priv, on bond devices created with
  ip link add type bond.

Subject: b43: LP-PHY: Begin implementing calibration & software RFKILL support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This implements the following calibration functions:
-Set TX IQCC
-Set TX Power by Index
-PR41573 workaround (incomplete, needs PHY reset)
-Calc RX IQ Comp
-PHY Cordic
-Run Samples
-Start/Stop TX Tone
-part of PAPD Cal TX Power
-RX I/Q Calibration
-The basic structure of the periodic calibration wrapper

Software RFKILL (required by calibration) is also implemented in
this round.

Subject: ath9k_hw: distinguish single-chip solutions on initial probe print

Devices with external radios have revisions which we can count on.
On single chip solutions these EEPROM values for these radio revision
also exist but are not meaningful as the radios are embedded onto the
same chip. Each single-chip device evolves together as one device.

We had 0x9912 but AR_PHY_SPECTRAL_SCAN is 0x9910. By using the
0x9912 we were making the hardware unresponsive. This allows us
to move forward with hardware reset on ar9271 on the ath9k_htc
driver.

Subject: mac80211: remove RX_FLAG_RADIOTAP

While there may be a case for a driver adding its
own bits of radiotap information, none currently
does. Also, drivers would have to copy the code
to generate the radiotap bits that now mac80211
generates. If some driver in the future needs to
add some driver-specific information I'd expect
that to be in a radiotap vendor namespace and we
can add a different way of passing such data up
and having mac80211 include it.

Additionally, rename IEEE80211_CONF_RADIOTAP to
IEEE80211_CONF_MONITOR since it's still used by
b43(legacy) to obtain per-frame timestamps.

The purpose of this patch is to simplify the RX
code in mac80211 to make it easier to add paged
skb support.

Subject: strip: move driver to staging

Move the strip ("Starmode Radio IP") driver to drivers/staging.  For
several years this driver has only seen API "bombing-run" changes, and
few people ever had the hardware.  This driver represents unnecessary
ongoing maintenance for no clear benefit.

This patch brought to you by the "hacking" session at the 2009 Kernel
Summit in Tokyo, Japan...

- * strip.c	This module implements Starmode Radio IP (STRIP)
- *		for kernel-based devices like TTY.  It interfaces between a
- *		raw TTY, and the kernel's INET protocol layers (via DDI).
- *
- * Version:	@(#)strip.c	1.3	July 1997
- *
- * Author:	Stuart Cheshire <cheshire@cs.stanford.edu>
- *
- * Fixes:	v0.9 12th Feb 1996 (SC)
- *		New byte stuffing (2+6 run-length encoding)
- *		New watchdog timer task
- *		New Protocol key (SIP0)
- *		
- *		v0.9.1 3rd March 1996 (SC)
- *		Changed to dynamic device allocation -- no more compile
- *		time (or boot time) limit on the number of STRIP devices.
- *		
- *		v0.9.2 13th March 1996 (SC)
- *		Uses arp cache lookups (but doesn't send arp packets yet)
- *		
- *		v0.9.3 17th April 1996 (SC)
- *		Fixed bug where STR_ERROR flag was getting set unneccessarily
- *		(causing otherwise good packets to be unneccessarily dropped)
- *		
- *		v0.9.4 27th April 1996 (SC)
- *		First attempt at using "&COMMAND" Starmode AT commands
- *		
- *		v0.9.5 29th May 1996 (SC)
- *		First attempt at sending (unicast) ARP packets
- *		
- *		v0.9.6 5th June 1996 (Elliot)
- *		Put "message level" tags in every "printk" statement
- *		
- *		v0.9.7 13th June 1996 (laik)
- *		Added support for the /proc fs
- *
- *              v0.9.8 July 1996 (Mema)
- *              Added packet logging
- *
- *              v1.0 November 1996 (SC)
- *              Fixed (severe) memory leaks in the /proc fs code
- *              Fixed race conditions in the logging code
- *
- *              v1.1 January 1997 (SC)
- *              Deleted packet logging (use tcpdump instead)
- *              Added support for Metricom Firmware v204 features
- *              (like message checksums)
- *
- *              v1.2 January 1997 (SC)
- *              Put portables list back in
- *
- *              v1.3 July 1997 (SC)
- *              Made STRIP driver set the radio's baud rate automatically.
- *              It is no longer necessarily to manually set the radio's
- *              rate permanently to 115200 -- the driver handles setting
- *              the rate automatically.

- * Note: manual_dev_addr hack
- * 
- * It is not possible to change the hardware address of a Metricom radio,
- * or to send packets with a user-specified hardware source address, thus
- * trying to manually set a hardware source address is a questionable
- * thing to do.  However, if the user *does* manually set the hardware
- * source address of a STRIP interface, then the kernel will believe it,
- * and use it in certain places. For example, the hardware address listed
- * by ifconfig will be the manual address, not the true one.
- * (Both addresses are listed in /proc/net/strip.)
- * Also, ARP packets will be sent out giving the user-specified address as
- * the source address, not the real address. This is dangerous, because
- * it means you won't receive any replies -- the ARP replies will go to
- * the specified address, which will be some other radio. The case where
- * this is useful is when that other radio is also connected to the same
- * machine. This allows you to connect a pair of radios to one machine,
- * and to use one exclusively for inbound traffic, and the other
- * exclusively for outbound traffic. Pretty neat, huh?
- * 
- * Here's the full procedure to set this up:
- * 
- * 1. "slattach" two interfaces, e.g. st0 for outgoing packets,
- *    and st1 for incoming packets
- * 
- * 2. "ifconfig" st0 (outbound radio) to have the hardware address
- *    which is the real hardware address of st1 (inbound radio).
- *    Now when it sends out packets, it will masquerade as st1, and
- *    replies will be sent to that radio, which is exactly what we want.
- * 
- * 3. Set the route table entry ("route add default ..." or
- *    "route add -net ...", as appropriate) to send packets via the st0
- *    interface (outbound radio). Do not add any route which sends packets
- *    out via the st1 interface -- that radio is for inbound traffic only.
- * 
- * 4. "ifconfig" st1 (inbound radio) to have hardware address zero.
- *    This tells the STRIP driver to "shut down" that interface and not
- *    send any packets through it. In particular, it stops sending the
- *    periodic gratuitous ARP packets that a STRIP interface normally sends.
- *    Also, when packets arrive on that interface, it will search the
- *    interface list to see if there is another interface who's manual
- *    hardware address matches its own real address (i.e. st0 in this
- *    example) and if so it will transfer ownership of the skbuff to
- *    that interface, so that it looks to the kernel as if the packet
- *    arrived on that interface. This is necessary because when the
- *    kernel sends an ARP packet on st0, it expects to get a reply on
- *    st0, and if it sees the reply come from st1 then it will ignore
- *    it (to be accurate, it puts the entry in the ARP table, but
- *    labelled in such a way that st0 can't use it).
- * 
- * Thanks to Petros Maniatis for coming up with the idea of splitting
- * inbound and outbound traffic between two interfaces, which turned
- * out to be really easy to implement, even if it is a bit of a hack.
- * 
- * Having set a manual address on an interface, you can restore it
- * to automatic operation (where the address is automatically kept
- * consistent with the real address of the radio) by setting a manual
- * address of all ones, e.g. "ifconfig st0 hw strip FFFFFFFFFFFF"
- * This 'turns off' manual override mode for the device address.
- * 
- * Note: The IEEE 802 headers reported in tcpdump will show the *real*
- * radio addresses the packets were sent and received from, so that you
- * can see what is really going on with packets, and which interfaces
- * they are really going through.

+	---help---
+	  Say Y if you have a Metricom radio and intend to use Starmode Radio
+	  IP. STRIP is a radio protocol developed for the MosquitoNet project
+	  to send Internet traffic using Metricom radios.  Metricom radios are
+	  small, battery powered, 100kbit/sec packet radio transceivers, about
+	  the size and weight of a cellular telephone. (You may also have heard
+	  them called "Metricom modems" but we avoid the term "modem" because
+	  it misleads many people into thinking that you can plug a Metricom
+	  modem into a phone line and use it as a modem.)
+
+	  You can use STRIP on any Linux machine with a serial port, although
+	  it is obviously most useful for people with laptop computers. If you
+	  think you might get a Metricom radio in the future, there is no harm
+	  in saying Y to STRIP now, except that it makes the kernel a bit
+	  bigger.
+
+	  To compile this as a module, choose M here: the module will be
+	  called strip.

+ * strip.c	This module implements Starmode Radio IP (STRIP)
+ *		for kernel-based devices like TTY.  It interfaces between a
+ *		raw TTY, and the kernel's INET protocol layers (via DDI).
+ *
+ * Version:	@(#)strip.c	1.3	July 1997
+ *
+ * Author:	Stuart Cheshire <cheshire@cs.stanford.edu>
+ *
+ * Fixes:	v0.9 12th Feb 1996 (SC)
+ *		New byte stuffing (2+6 run-length encoding)
+ *		New watchdog timer task
+ *		New Protocol key (SIP0)
+ *		
+ *		v0.9.1 3rd March 1996 (SC)
+ *		Changed to dynamic device allocation -- no more compile
+ *		time (or boot time) limit on the number of STRIP devices.
+ *		
+ *		v0.9.2 13th March 1996 (SC)
+ *		Uses arp cache lookups (but doesn't send arp packets yet)
+ *		
+ *		v0.9.3 17th April 1996 (SC)
+ *		Fixed bug where STR_ERROR flag was getting set unneccessarily
+ *		(causing otherwise good packets to be unneccessarily dropped)
+ *		
+ *		v0.9.4 27th April 1996 (SC)
+ *		First attempt at using "&COMMAND" Starmode AT commands
+ *		
+ *		v0.9.5 29th May 1996 (SC)
+ *		First attempt at sending (unicast) ARP packets
+ *		
+ *		v0.9.6 5th June 1996 (Elliot)
+ *		Put "message level" tags in every "printk" statement
+ *		
+ *		v0.9.7 13th June 1996 (laik)
+ *		Added support for the /proc fs
+ *
+ *              v0.9.8 July 1996 (Mema)
+ *              Added packet logging
+ *
+ *              v1.0 November 1996 (SC)
+ *              Fixed (severe) memory leaks in the /proc fs code
+ *              Fixed race conditions in the logging code
+ *
+ *              v1.1 January 1997 (SC)
+ *              Deleted packet logging (use tcpdump instead)
+ *              Added support for Metricom Firmware v204 features
+ *              (like message checksums)
+ *
+ *              v1.2 January 1997 (SC)
+ *              Put portables list back in
+ *
+ *              v1.3 July 1997 (SC)
+ *              Made STRIP driver set the radio's baud rate automatically.
+ *              It is no longer necessarily to manually set the radio's
+ *              rate permanently to 115200 -- the driver handles setting
+ *              the rate automatically.

+ * Note: manual_dev_addr hack
+ * 
+ * It is not possible to change the hardware address of a Metricom radio,
+ * or to send packets with a user-specified hardware source address, thus
+ * trying to manually set a hardware source address is a questionable
+ * thing to do.  However, if the user *does* manually set the hardware
+ * source address of a STRIP interface, then the kernel will believe it,
+ * and use it in certain places. For example, the hardware address listed
+ * by ifconfig will be the manual address, not the true one.
+ * (Both addresses are listed in /proc/net/strip.)
+ * Also, ARP packets will be sent out giving the user-specified address as
+ * the source address, not the real address. This is dangerous, because
+ * it means you won't receive any replies -- the ARP replies will go to
+ * the specified address, which will be some other radio. The case where
+ * this is useful is when that other radio is also connected to the same
+ * machine. This allows you to connect a pair of radios to one machine,
+ * and to use one exclusively for inbound traffic, and the other
+ * exclusively for outbound traffic. Pretty neat, huh?
+ * 
+ * Here's the full procedure to set this up:
+ * 
+ * 1. "slattach" two interfaces, e.g. st0 for outgoing packets,
+ *    and st1 for incoming packets
+ * 
+ * 2. "ifconfig" st0 (outbound radio) to have the hardware address
+ *    which is the real hardware address of st1 (inbound radio).
+ *    Now when it sends out packets, it will masquerade as st1, and
+ *    replies will be sent to that radio, which is exactly what we want.
+ * 
+ * 3. Set the route table entry ("route add default ..." or
+ *    "route add -net ...", as appropriate) to send packets via the st0
+ *    interface (outbound radio). Do not add any route which sends packets
+ *    out via the st1 interface -- that radio is for inbound traffic only.
+ * 
+ * 4. "ifconfig" st1 (inbound radio) to have hardware address zero.
+ *    This tells the STRIP driver to "shut down" that interface and not
+ *    send any packets through it. In particular, it stops sending the
+ *    periodic gratuitous ARP packets that a STRIP interface normally sends.
+ *    Also, when packets arrive on that interface, it will search the
+ *    interface list to see if there is another interface who's manual
+ *    hardware address matches its own real address (i.e. st0 in this
+ *    example) and if so it will transfer ownership of the skbuff to
+ *    that interface, so that it looks to the kernel as if the packet
+ *    arrived on that interface. This is necessary because when the
+ *    kernel sends an ARP packet on st0, it expects to get a reply on
+ *    st0, and if it sees the reply come from st1 then it will ignore
+ *    it (to be accurate, it puts the entry in the ARP table, but
+ *    labelled in such a way that st0 can't use it).
+ * 
+ * Thanks to Petros Maniatis for coming up with the idea of splitting
+ * inbound and outbound traffic between two interfaces, which turned
+ * out to be really easy to implement, even if it is a bit of a hack.
+ * 
+ * Having set a manual address on an interface, you can restore it
+ * to automatic operation (where the address is automatically kept
+ * consistent with the real address of the radio) by setting a manual
+ * address of all ones, e.g. "ifconfig st0 hw strip FFFFFFFFFFFF"
+ * This 'turns off' manual override mode for the device address.
+ * 
+ * Note: The IEEE 802 headers reported in tcpdump will show the *real*
+ * radio addresses the packets were sent and received from, so that you
+ * can see what is really going on with packets, and which interfaces
+ * they are really going through.

From e38879efd336fb78b288dcebdc9ca030fd24f449 Mon Sep 17 00:00:00 2001

Subject: arlan: move driver to staging

Move the arlan driver to drivers/staging.  This is another pre-802.11
driver that has seen virtually no non-API-fixup activity in years, and
for which no active hardware is likely to still exist.  This driver
represents unnecessary ongoing maintenance for no clear benefit.

This patch brought to you by the "hacking" session at the 2009 Kernel
Summit in Tokyo, Japan...

-
-	  The driver is built as two modules, arlan and arlan-proc. The latter
-	  is the /proc interface and is not needed most of time.
-
-	  On some computers the card ends up in non-valid state after some
-	  time. Use a ping-reset script to clear it.

+config ARLAN
+	tristate "Aironet Arlan 655 & IC2200 DS support"
+	depends on ISA && !64BIT
+	select WIRELESS_EXT
+	---help---
+	  Aironet makes Arlan, a class of wireless LAN adapters. These use the
+	  www.Telxon.com chip, which is also used on several similar cards.
+	  This driver is tested on the 655 and IC2200 series cards. Look at
+	  <http://www.ylenurme.ee/~elmer/655/> for the latest information.
+
+	  The driver is built as two modules, arlan and arlan-proc. The latter
+	  is the /proc interface and is not needed most of time.
+
+	  On some computers the card ends up in non-valid state after some
+	  time. Use a ping-reset script to clear it.

From 0234f84ebb00d36c48062befa5436eef36b71ccd Mon Sep 17 00:00:00 2001

Subject: wavelan: move driver to staging

Move the wavelan driver to drivers/staging.  This is another pre-802.11
driver that has seen virtually no non-API-fixup activity in years, and
for which no active hardware is likely to still exist.  This driver
represents unnecessary ongoing maintenance for no clear benefit.

This patch brought to you by the "hacking" session at the 2009 Kernel
Summit in Tokyo, Japan...

-/*
- * This driver provides a Linux interface to the WaveLAN ISA hardware.
- * The WaveLAN is a product of Lucent (http://www.wavelan.com/).
- * This division was formerly part of NCR and then AT&T.
- * WaveLANs are also distributed by DEC (RoamAbout DS) and Digital Ocean.
- *
- * To learn how to use this driver, read the NET3 HOWTO.
- * If you want to exploit the many other functionalities, read the comments
- * in the code.
- *
- * This driver is the result of the effort of many people (see below).
- */
-
-/* ------------------------ SPECIFIC NOTES ------------------------ */
-/*
- * Web page
- * --------
- *	I try to maintain a web page with the Wireless LAN Howto at :
- *	    http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Wavelan.html
- *
- * SMP
- * ---
- *	We now are SMP compliant (I eventually fixed the remaining bugs).
- *	The driver has been tested on a dual P6-150 and survived my usual
- *	set of torture tests.
- *	Anyway, I spent enough time chasing interrupt re-entrancy during
- *	errors or reconfigure, and I designed the locked/unlocked sections
- *	of the driver with great care, and with the recent addition of
- *	the spinlock (thanks to the new API), we should be quite close to
- *	the truth.
- *	The SMP/IRQ locking is quite coarse and conservative (i.e. not fast),
- *	but better safe than sorry (especially at 2 Mb/s ;-).
- *
- *	I have also looked into disabling only our interrupt on the card
- *	(via HACR) instead of all interrupts in the processor (via cli),
- *	so that other driver are not impacted, and it look like it's
- *	possible, but it's very tricky to do right (full of races). As
- *	the gain would be mostly for SMP systems, it can wait...
- *
- * Debugging and options
- * ---------------------
- *	You will find below a set of '#define" allowing a very fine control
- *	on the driver behaviour and the debug messages printed.
- *	The main options are :
- *	o SET_PSA_CRC, to have your card correctly recognised by
- *	  an access point and the Point-to-Point diagnostic tool.
- *	o USE_PSA_CONFIG, to read configuration from the PSA (EEprom)
- *	  (otherwise we always start afresh with some defaults)
- *
- * wavelan.o is too darned big
- * ---------------------------
- *	That's true!  There is a very simple way to reduce the driver
- *	object by 33%!  Comment out the following line:
- *		#include <linux/wireless.h>
- *	Other compile options can also reduce the size of it...
- *
- * MAC address and hardware detection:
- * -----------------------------------
- *	The detection code for the WaveLAN checks that the first three
- *	octets of the MAC address fit the company code.  This type of
- *	detection works well for AT&T cards (because the AT&T code is
- *	hardcoded in wavelan.h), but of course will fail for other
- *	manufacturers.
- *
- *	If you are sure that your card is derived from the WaveLAN,
- *	here is the way to configure it:
- *	1) Get your MAC address
- *		a) With your card utilities (wfreqsel, instconf, etc.)
- *		b) With the driver:
- *			o compile the kernel with DEBUG_CONFIG_INFO enabled
- *			o Boot and look the card messages
- *	2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan.h)
- *	3) Compile and verify
- *	4) Send me the MAC code.  I will include it in the next version.
- *

-
-/* --------------------- WIRELESS EXTENSIONS --------------------- */
-/*
- * This driver is the first to support "wireless extensions".
- * This set of extensions provides a standard way to control the wireless
- * characteristics of the hardware.  Applications such as mobile IP may
- * take advantage of it.
- *
- * It might be a good idea as well to fetch the wireless tools to
- * configure the device and play a bit.

-/* --------------------------- HISTORY --------------------------- */
-/*
- * This is based on information in the drivers' headers. It may not be
- * accurate, and I guarantee only my best effort.
- *
- * The history of the WaveLAN drivers is as complicated as the history of
- * the WaveLAN itself (NCR -> AT&T -> Lucent).
- *
- * It all started with Anders Klemets <klemets@paul.rutgers.edu>
- * writing a WaveLAN ISA driver for the Mach microkernel.  Girish
- * Welling <welling@paul.rutgers.edu> had also worked on it.
- * Keith Moore modified this for the PCMCIA hardware.
- * 
- * Robert Morris <rtm@das.harvard.edu> ported these two drivers to BSDI
- * and added specific PCMCIA support (there is currently no equivalent
- * of the PCMCIA package under BSD).
- *
- * Jim Binkley <jrb@cs.pdx.edu> ported both BSDI drivers to FreeBSD.
- *
- * Bruce Janson <bruce@cs.usyd.edu.au> ported the BSDI ISA driver to Linux.
- *
- * Anthony D. Joseph <adj@lcs.mit.edu> started to modify Bruce's driver
- * (with help of the BSDI PCMCIA driver) for PCMCIA.
- * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished this work.
- * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
- * 2.00 cards correctly (2.4 GHz with frequency selection).
- * David Hinds <dahinds@users.sourceforge.net> integrated the whole in his
- * PCMCIA package (and bug corrections).
- *
- * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some
- * patches to the PCMCIA driver.  Later, I added code in the ISA driver
- * for Wireless Extensions and full support of frequency selection
- * cards.  Then, I did the same to the PCMCIA driver, and did some
- * reorganisation.  Finally, I came back to the ISA driver to
- * upgrade it at the same level as the PCMCIA one and reorganise
- * the code.
- * Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me
- * much needed information on the WaveLAN hardware.

-/* ------------------------- IMPROVEMENTS ------------------------- */
-/*
- * I proudly present:
- *
- * Changes made in first pre-release:
- * ----------------------------------
- *	- reorganisation of the code, function name change
- *	- creation of private header (wavelan.p.h)
- *	- reorganised debug messages
- *	- more comments, history, etc.
- *	- mmc_init:  configure the PSA if not done
- *	- mmc_init:  correct default value of level threshold for PCMCIA
- *	- mmc_init:  2.00 detection better code for 2.00 initialization
- *	- better info at startup
- *	- IRQ setting (note:  this setting is permanent)
- *	- watchdog:  change strategy (and solve module removal problems)
- *	- add wireless extensions (ioctl and get_wireless_stats)
- *	  get/set nwid/frequency on fly, info for /proc/net/wireless
- *	- more wireless extensions:  SETSPY and GETSPY
- *	- make wireless extensions optional
- *	- private ioctl to set/get quality and level threshold, histogram
- *	- remove /proc/net/wavelan
- *	- suppress useless stuff from lp (net_local)
- *	- kernel 2.1 support (copy_to/from_user instead of memcpy_to/fromfs)
- *	- add message level (debug stuff in /var/adm/debug and errors not
- *	  displayed at console and still in /var/adm/messages)
- *	- multi device support
- *	- start fixing the probe (init code)
- *	- more inlines
- *	- man page
- *	- many other minor details and cleanups
- *
- * Changes made in second pre-release:
- * -----------------------------------
- *	- clean up init code (probe and module init)
- *	- better multiple device support (module)
- *	- name assignment (module)
- *
- * Changes made in third pre-release:
- * ----------------------------------
- *	- be more conservative on timers
- *	- preliminary support for multicast (I still lack some details)
- *
- * Changes made in fourth pre-release:
- * -----------------------------------
- *	- multicast (revisited and finished)
- *	- avoid reset in set_multicast_list (a really big hack)
- *	  if somebody could apply this code for other i82586 based drivers
- *	- share onboard memory 75% RU and 25% CU (instead of 50/50)
- *
- * Changes made for release in 2.1.15:
- * -----------------------------------
- *	- change the detection code for multi manufacturer code support
- *
- * Changes made for release in 2.1.17:
- * -----------------------------------
- *	- update to wireless extensions changes
- *	- silly bug in card initial configuration (psa_conf_status)
- *
- * Changes made for release in 2.1.27 & 2.0.30:
- * --------------------------------------------
- *	- small bug in debug code (probably not the last one...)
- *	- remove extern keyword for wavelan_probe()
- *	- level threshold is now a standard wireless extension (version 4 !)
- *	- modules parameters types (new module interface)
- *
- * Changes made for release in 2.1.36:
- * -----------------------------------
- *	- byte count stats (courtesy of David Hinds)
- *	- remove dev_tint stuff (courtesy of David Hinds)
- *	- encryption setting from Brent Elphick (thanks a lot!)
- *	- 'ioaddr' to 'u_long' for the Alpha (thanks to Stanislav Sinyagin)
- *
- * Other changes (not by me) :
- * -------------------------
- *	- Spelling and gramar "rectification".
- *
- * Changes made for release in 2.0.37 & 2.2.2 :
- * ------------------------------------------
- *	- Correct status in /proc/net/wireless
- *	- Set PSA CRC to make PtP diagnostic tool happy (Bob Gray)
- *	- Module init code don't fail if we found at least one card in
- *	  the address list (Karlis Peisenieks)
- *	- Missing parenthesis (Christopher Peterson)
- *	- Correct i82586 configuration parameters
- *	- Encryption initialisation bug (Robert McCormack)
- *	- New mac addresses detected in the probe
- *	- Increase watchdog for busy environments
- *
- * Changes made for release in 2.0.38 & 2.2.7 :
- * ------------------------------------------
- *	- Correct the reception logic to better report errors and avoid
- *	  sending bogus packet up the stack
- *	- Delay RU config to avoid corrupting first received packet
- *	- Change config completion code (to actually check something)
- *	- Avoid reading out of bound in skbuf to transmit
- *	- Rectify a lot of (useless) debugging code
- *	- Change the way to `#ifdef SET_PSA_CRC'
- *
- * Changes made for release in 2.2.11 & 2.3.13 :
- * -------------------------------------------
- *	- Change e-mail and web page addresses
- *	- Watchdog timer is now correctly expressed in HZ, not in jiffies
- *	- Add channel number to the list of frequencies in range
- *	- Add the (short) list of bit-rates in range
- *	- Developp a new sensitivity... (sens.value & sens.fixed)
- *
- * Changes made for release in 2.2.14 & 2.3.23 :
- * -------------------------------------------
- *	- Fix check for root permission (break instead of exit)
- *	- New nwid & encoding setting (Wireless Extension 9)
- *
- * Changes made for release in 2.3.49 :
- * ----------------------------------
- *	- Indentation reformating (Alan)
- *	- Update to new network API (softnet - 2.3.43) :
- *		o replace dev->tbusy (Alan)
- *		o replace dev->tstart (Alan)
- *		o remove dev->interrupt (Alan)
- *		o add SMP locking via spinlock in splxx (me)
- *		o add spinlock in interrupt handler (me)
- *		o use kernel watchdog instead of ours (me)
- *		o increase watchdog timeout (kernel is more sensitive) (me)
- *		o verify that all the changes make sense and work (me)
- *	- Fixup a potential gotcha when reconfiguring and thighten a bit
- *		the interactions with Tx queue.
- *
- * Changes made for release in 2.4.0 :
- * ---------------------------------
- *	- Fix spinlock stupid bugs that I left in. The driver is now SMP
- *		compliant and doesn't lockup at startup.
- *
- * Changes made for release in 2.5.2 :
- * ---------------------------------
- *	- Use new driver API for Wireless Extensions :
- *		o got rid of wavelan_ioctl()
- *		o use a bunch of iw_handler instead
- *
- * Changes made for release in 2.5.35 :
- * ----------------------------------
- *	- Set dev->trans_start to avoid filling the logs
- *	- Handle better spurious/bogus interrupt
- *	- Avoid deadlocks in mmc_out()/mmc_in()
- *
- * Wishes & dreams:
- * ----------------
- *	- roaming (see Pcmcia driver)

-/*
- * This driver provide a Linux interface to the Wavelan Pcmcia hardware
- * The Wavelan is a product of Lucent (http://www.wavelan.com/).
- * This division was formerly part of NCR and then AT&T.
- * Wavelan are also distributed by DEC (RoamAbout DS)...
- *
- * To know how to use this driver, read the PCMCIA HOWTO.
- * If you want to exploit the many other fonctionalities, look comments
- * in the code...
- *
- * This driver is the result of the effort of many peoples (see below).
- */
-
-/* ------------------------ SPECIFIC NOTES ------------------------ */
-/*
- * Web page
- * --------
- *	I try to maintain a web page with the Wireless LAN Howto at :
- *	    http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Wavelan.html
- *
- * SMP
- * ---
- *	We now are SMP compliant (I eventually fixed the remaining bugs).
- *	The driver has been tested on a dual P6-150 and survived my usual
- *	set of torture tests.
- *	Anyway, I spent enough time chasing interrupt re-entrancy during
- *	errors or reconfigure, and I designed the locked/unlocked sections
- *	of the driver with great care, and with the recent addition of
- *	the spinlock (thanks to the new API), we should be quite close to
- *	the truth.
- *	The SMP/IRQ locking is quite coarse and conservative (i.e. not fast),
- *	but better safe than sorry (especially at 2 Mb/s ;-).
- *
- *	I have also looked into disabling only our interrupt on the card
- *	(via HACR) instead of all interrupts in the processor (via cli),
- *	so that other driver are not impacted, and it look like it's
- *	possible, but it's very tricky to do right (full of races). As
- *	the gain would be mostly for SMP systems, it can wait...
- *
- * Debugging and options
- * ---------------------
- *	You will find below a set of '#define" allowing a very fine control
- *	on the driver behaviour and the debug messages printed.
- *	The main options are :
- *	o WAVELAN_ROAMING, for the experimental roaming support.
- *	o SET_PSA_CRC, to have your card correctly recognised by
- *	  an access point and the Point-to-Point diagnostic tool.
- *	o USE_PSA_CONFIG, to read configuration from the PSA (EEprom)
- *	  (otherwise we always start afresh with some defaults)
- *
- * wavelan_cs.o is darn too big
- * -------------------------
- *	That's true ! There is a very simple way to reduce the driver
- *	object by 33% (yes !). Comment out the following line :
- *		#include <linux/wireless.h>
- *	Other compile options can also reduce the size of it...
- *
- * MAC address and hardware detection :
- * ----------------------------------
- *	The detection code of the wavelan chech that the first 3
- *	octets of the MAC address fit the company code. This type of
- *	detection work well for AT&T cards (because the AT&T code is
- *	hardcoded in wavelan_cs.h), but of course will fail for other
- *	manufacturer.
- *
- *	If you are sure that your card is derived from the wavelan,
- *	here is the way to configure it :
- *	1) Get your MAC address
- *		a) With your card utilities (wfreqsel, instconf, ...)
- *		b) With the driver :
- *			o compile the kernel with DEBUG_CONFIG_INFO enabled
- *			o Boot and look the card messages
- *	2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan_cs.h)
- *	3) Compile & verify
- *	4) Send me the MAC code - I will include it in the next version...
- *
- */
-
-/* --------------------- WIRELESS EXTENSIONS --------------------- */
-/*
- * This driver is the first one to support "wireless extensions".
- * This set of extensions provide you some way to control the wireless
- * caracteristics of the hardware in a standard way and support for
- * applications for taking advantage of it (like Mobile IP).
- *
- * It might be a good idea as well to fetch the wireless tools to
- * configure the device and play a bit.

-/* --------------------------- HISTORY --------------------------- */
-/*
- * The history of the Wavelan drivers is as complicated as history of
- * the Wavelan itself (NCR -> AT&T -> Lucent).
- *
- * All started with Anders Klemets <klemets@paul.rutgers.edu>,
- * writing a Wavelan ISA driver for the MACH microkernel. Girish
- * Welling <welling@paul.rutgers.edu> had also worked on it.
- * Keith Moore modify this for the Pcmcia hardware.
- * 
- * Robert Morris <rtm@das.harvard.edu> port these two drivers to BSDI
- * and add specific Pcmcia support (there is currently no equivalent
- * of the PCMCIA package under BSD...).
- *
- * Jim Binkley <jrb@cs.pdx.edu> port both BSDI drivers to FreeBSD.
- *
- * Bruce Janson <bruce@cs.usyd.edu.au> port the BSDI ISA driver to Linux.
- *
- * Anthony D. Joseph <adj@lcs.mit.edu> started modify Bruce driver
- * (with help of the BSDI PCMCIA driver) for PCMCIA.
- * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished is work.
- * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
- * correctly 2.00 cards (2.4 GHz with frequency selection).
- * David Hinds <dahinds@users.sourceforge.net> integrated the whole in his
- * Pcmcia package (+ bug corrections).
- *
- * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some
- * patchs to the Pcmcia driver. After, I added code in the ISA driver
- * for Wireless Extensions and full support of frequency selection
- * cards. Now, I'm doing the same to the Pcmcia driver + some
- * reorganisation.
- * Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me
- * much needed informations on the Wavelan hardware.

- *
- * Changes made for release in 3.1.2 :
- * ---------------------------------
- *	- Fix check for root permission (break instead of exit)
- *	- New nwid & encoding setting (Wireless Extension 9)
- *
- * Changes made for release in 3.1.12 :
- * ----------------------------------
- *	- reworked wv_82593_cmd to avoid using the IRQ handler and doing
- *	  ugly things with interrupts.
- *	- Add IRQ protection in 82593_config/ru_start/ru_stop/watchdog
- *	- Update to new network API (softnet - 2.3.43) :

+/************************** DOCUMENTATION ***************************/
+/*
+ * This driver provides a Linux interface to the WaveLAN ISA hardware.
+ * The WaveLAN is a product of Lucent (http://www.wavelan.com/).
+ * This division was formerly part of NCR and then AT&T.
+ * WaveLANs are also distributed by DEC (RoamAbout DS) and Digital Ocean.
+ *
+ * To learn how to use this driver, read the NET3 HOWTO.
+ * If you want to exploit the many other functionalities, read the comments
+ * in the code.
+ *
+ * This driver is the result of the effort of many people (see below).
+ */
+
+/* ------------------------ SPECIFIC NOTES ------------------------ */
+/*
+ * Web page
+ * --------
+ *	I try to maintain a web page with the Wireless LAN Howto at :
+ *	    http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Wavelan.html
+ *
+ * SMP
+ * ---
+ *	We now are SMP compliant (I eventually fixed the remaining bugs).
+ *	The driver has been tested on a dual P6-150 and survived my usual
+ *	set of torture tests.
+ *	Anyway, I spent enough time chasing interrupt re-entrancy during
+ *	errors or reconfigure, and I designed the locked/unlocked sections
+ *	of the driver with great care, and with the recent addition of
+ *	the spinlock (thanks to the new API), we should be quite close to
+ *	the truth.
+ *	The SMP/IRQ locking is quite coarse and conservative (i.e. not fast),
+ *	but better safe than sorry (especially at 2 Mb/s ;-).
+ *
+ *	I have also looked into disabling only our interrupt on the card
+ *	(via HACR) instead of all interrupts in the processor (via cli),
+ *	so that other driver are not impacted, and it look like it's
+ *	possible, but it's very tricky to do right (full of races). As
+ *	the gain would be mostly for SMP systems, it can wait...
+ *
+ * Debugging and options
+ * ---------------------
+ *	You will find below a set of '#define" allowing a very fine control
+ *	on the driver behaviour and the debug messages printed.
+ *	The main options are :
+ *	o SET_PSA_CRC, to have your card correctly recognised by
+ *	  an access point and the Point-to-Point diagnostic tool.
+ *	o USE_PSA_CONFIG, to read configuration from the PSA (EEprom)
+ *	  (otherwise we always start afresh with some defaults)
+ *
+ * wavelan.o is too darned big
+ * ---------------------------
+ *	That's true!  There is a very simple way to reduce the driver
+ *	object by 33%!  Comment out the following line:
+ *		#include <linux/wireless.h>
+ *	Other compile options can also reduce the size of it...
+ *
+ * MAC address and hardware detection:
+ * -----------------------------------
+ *	The detection code for the WaveLAN checks that the first three
+ *	octets of the MAC address fit the company code.  This type of
+ *	detection works well for AT&T cards (because the AT&T code is
+ *	hardcoded in wavelan.h), but of course will fail for other
+ *	manufacturers.
+ *
+ *	If you are sure that your card is derived from the WaveLAN,
+ *	here is the way to configure it:
+ *	1) Get your MAC address
+ *		a) With your card utilities (wfreqsel, instconf, etc.)
+ *		b) With the driver:
+ *			o compile the kernel with DEBUG_CONFIG_INFO enabled
+ *			o Boot and look the card messages
+ *	2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan.h)
+ *	3) Compile and verify
+ *	4) Send me the MAC code.  I will include it in the next version.
+ *
+ */
+
+/* --------------------- WIRELESS EXTENSIONS --------------------- */
+/*
+ * This driver is the first to support "wireless extensions".
+ * This set of extensions provides a standard way to control the wireless
+ * characteristics of the hardware.  Applications such as mobile IP may
+ * take advantage of it.
+ *
+ * It might be a good idea as well to fetch the wireless tools to
+ * configure the device and play a bit.

+/* --------------------------- HISTORY --------------------------- */
+/*
+ * This is based on information in the drivers' headers. It may not be
+ * accurate, and I guarantee only my best effort.
+ *
+ * The history of the WaveLAN drivers is as complicated as the history of
+ * the WaveLAN itself (NCR -> AT&T -> Lucent).
+ *
+ * It all started with Anders Klemets <klemets@paul.rutgers.edu>
+ * writing a WaveLAN ISA driver for the Mach microkernel.  Girish
+ * Welling <welling@paul.rutgers.edu> had also worked on it.
+ * Keith Moore modified this for the PCMCIA hardware.
+ * 
+ * Robert Morris <rtm@das.harvard.edu> ported these two drivers to BSDI
+ * and added specific PCMCIA support (there is currently no equivalent
+ * of the PCMCIA package under BSD).
+ *
+ * Jim Binkley <jrb@cs.pdx.edu> ported both BSDI drivers to FreeBSD.
+ *
+ * Bruce Janson <bruce@cs.usyd.edu.au> ported the BSDI ISA driver to Linux.
+ *
+ * Anthony D. Joseph <adj@lcs.mit.edu> started to modify Bruce's driver
+ * (with help of the BSDI PCMCIA driver) for PCMCIA.
+ * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished this work.
+ * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
+ * 2.00 cards correctly (2.4 GHz with frequency selection).
+ * David Hinds <dahinds@users.sourceforge.net> integrated the whole in his
+ * PCMCIA package (and bug corrections).
+ *
+ * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some
+ * patches to the PCMCIA driver.  Later, I added code in the ISA driver
+ * for Wireless Extensions and full support of frequency selection
+ * cards.  Then, I did the same to the PCMCIA driver, and did some
+ * reorganisation.  Finally, I came back to the ISA driver to
+ * upgrade it at the same level as the PCMCIA one and reorganise
+ * the code.
+ * Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me
+ * much needed information on the WaveLAN hardware.

+ * This driver provide a Linux interface to the Wavelan Pcmcia hardware
+ * The Wavelan is a product of Lucent (http://www.wavelan.com/).
+ * This division was formerly part of NCR and then AT&T.
+ * Wavelan are also distributed by DEC (RoamAbout DS)...
+ *
+ * To know how to use this driver, read the PCMCIA HOWTO.
+ * If you want to exploit the many other fonctionalities, look comments
+ * in the code...
+ *
+ * This driver is the result of the effort of many peoples (see below).
+ */
+
+/* ------------------------ SPECIFIC NOTES ------------------------ */
+/*
+ * Web page
+ * --------
+ *	I try to maintain a web page with the Wireless LAN Howto at :
+ *	    http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Wavelan.html
+ *
+ * SMP
+ * ---
+ *	We now are SMP compliant (I eventually fixed the remaining bugs).
+ *	The driver has been tested on a dual P6-150 and survived my usual
+ *	set of torture tests.
+ *	Anyway, I spent enough time chasing interrupt re-entrancy during
+ *	errors or reconfigure, and I designed the locked/unlocked sections
+ *	of the driver with great care, and with the recent addition of
+ *	the spinlock (thanks to the new API), we should be quite close to
+ *	the truth.
+ *	The SMP/IRQ locking is quite coarse and conservative (i.e. not fast),
+ *	but better safe than sorry (especially at 2 Mb/s ;-).
+ *
+ *	I have also looked into disabling only our interrupt on the card
+ *	(via HACR) instead of all interrupts in the processor (via cli),
+ *	so that other driver are not impacted, and it look like it's
+ *	possible, but it's very tricky to do right (full of races). As
+ *	the gain would be mostly for SMP systems, it can wait...
+ *
+ * Debugging and options
+ * ---------------------
+ *	You will find below a set of '#define" allowing a very fine control
+ *	on the driver behaviour and the debug messages printed.
+ *	The main options are :
+ *	o WAVELAN_ROAMING, for the experimental roaming support.
+ *	o SET_PSA_CRC, to have your card correctly recognised by
+ *	  an access point and the Point-to-Point diagnostic tool.
+ *	o USE_PSA_CONFIG, to read configuration from the PSA (EEprom)
+ *	  (otherwise we always start afresh with some defaults)
+ *
+ * wavelan_cs.o is darn too big
+ * -------------------------
+ *	That's true ! There is a very simple way to reduce the driver
+ *	object by 33% (yes !). Comment out the following line :
+ *		#include <linux/wireless.h>
+ *	Other compile options can also reduce the size of it...
+ *
+ * MAC address and hardware detection :
+ * ----------------------------------
+ *	The detection code of the wavelan chech that the first 3
+ *	octets of the MAC address fit the company code. This type of
+ *	detection work well for AT&T cards (because the AT&T code is
+ *	hardcoded in wavelan_cs.h), but of course will fail for other
+ *	manufacturer.
+ *
+ *	If you are sure that your card is derived from the wavelan,
+ *	here is the way to configure it :
+ *	1) Get your MAC address
+ *		a) With your card utilities (wfreqsel, instconf, ...)
+ *		b) With the driver :
+ *			o compile the kernel with DEBUG_CONFIG_INFO enabled
+ *			o Boot and look the card messages
+ *	2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan_cs.h)
+ *	3) Compile & verify
+ *	4) Send me the MAC code - I will include it in the next version...
+ *
+ */
+
+/* --------------------- WIRELESS EXTENSIONS --------------------- */
+/*
+ * This driver is the first one to support "wireless extensions".
+ * This set of extensions provide you some way to control the wireless
+ * caracteristics of the hardware in a standard way and support for
+ * applications for taking advantage of it (like Mobile IP).
+ *
+ * It might be a good idea as well to fetch the wireless tools to
+ * configure the device and play a bit.

+/* --------------------------- HISTORY --------------------------- */
+/*
+ * The history of the Wavelan drivers is as complicated as history of
+ * the Wavelan itself (NCR -> AT&T -> Lucent).
+ *
+ * All started with Anders Klemets <klemets@paul.rutgers.edu>,
+ * writing a Wavelan ISA driver for the MACH microkernel. Girish
+ * Welling <welling@paul.rutgers.edu> had also worked on it.
+ * Keith Moore modify this for the Pcmcia hardware.
+ * 
+ * Robert Morris <rtm@das.harvard.edu> port these two drivers to BSDI
+ * and add specific Pcmcia support (there is currently no equivalent
+ * of the PCMCIA package under BSD...).
+ *
+ * Jim Binkley <jrb@cs.pdx.edu> port both BSDI drivers to FreeBSD.
+ *
+ * Bruce Janson <bruce@cs.usyd.edu.au> port the BSDI ISA driver to Linux.
+ *
+ * Anthony D. Joseph <adj@lcs.mit.edu> started modify Bruce driver
+ * (with help of the BSDI PCMCIA driver) for PCMCIA.
+ * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished is work.
+ * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
+ * correctly 2.00 cards (2.4 GHz with frequency selection).
+ * David Hinds <dahinds@users.sourceforge.net> integrated the whole in his
+ * Pcmcia package (+ bug corrections).
+ *
+ * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some
+ * patchs to the Pcmcia driver. After, I added code in the ISA driver
+ * for Wireless Extensions and full support of frequency selection
+ * cards. Now, I'm doing the same to the Pcmcia driver + some
+ * reorganisation.
+ * Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me
+ * much needed informations on the Wavelan hardware.

+ *	- kill watchdog in hw_reset
+ *	- more 2.1 support (copy_to/from_user instead of memcpy_to/fromfs)

+ *
+ * Changes made in eigth release :
+ * -----------------------------
+ *	- Small bug in debug code (probably not the last one...)
+ *	- 1.2.13 support (thanks to Clark Woodworth)

Subject: netwave: move driver to staging

Move the netwave driver to drivers/staging.  This is another pre-802.11
driver that has seen virtually no non-API-fixup activity in years, and
for which no active hardware is likely to still exist.  This driver
represents unnecessary ongoing maintenance for no clear benefit.

This patch brought to you by the "hacking" session at the 2009 Kernel
Summit in Tokyo, Japan...

- * Filename:      netwave_cs.c
- * Version:       0.4.1
- * Description:   Netwave AirSurfer Wireless LAN PC Card driver
- * Status:        Experimental.
- * Authors:       John Markus Bjørndalen <johnm@cs.uit.no>

- * Revision History:
- *
- *   08-Nov-97 15:14:47   John Markus Bjørndalen <johnm@cs.uit.no>
- *    - Fixed some bugs in netwave_rx and cleaned it up a bit. 
- *      (One of the bugs would have destroyed packets when receiving
- *      multiple packets per interrupt). 
- *    - Cleaned up parts of newave_hw_xmit. 
- *    - A few general cleanups. 
- *   24-Oct-97 13:17:36   Dag Brattli <dagb@cs.uit.no>
- *    - Fixed netwave_rx receive function (got updated docs)
- *   Others:
- *    - Changed name from xircnw to netwave, take a look at 
- *      http://www.netwave-wireless.com
- *    - Some reorganizing of the code
- *    - Removed possible race condition between interrupt handler and transmit
- *      function
- *    - Started to add wireless extensions, but still needs some coding
- *    - Added watchdog for better handling of transmission timeouts 
- *      (hopefully this works better)

+ *
+ * Revision History:
+ *
+ *   08-Nov-97 15:14:47   John Markus Bjørndalen <johnm@cs.uit.no>
+ *    - Fixed some bugs in netwave_rx and cleaned it up a bit. 
+ *      (One of the bugs would have destroyed packets when receiving
+ *      multiple packets per interrupt). 
+ *    - Cleaned up parts of newave_hw_xmit. 
+ *    - A few general cleanups. 
+ *   24-Oct-97 13:17:36   Dag Brattli <dagb@cs.uit.no>
+ *    - Fixed netwave_rx receive function (got updated docs)
+ *   Others:
+ *    - Changed name from xircnw to netwave, take a look at 
+ *      http://www.netwave-wireless.com
+ *    - Some reorganizing of the code
+ *    - Removed possible race condition between interrupt handler and transmit
+ *      function
+ *    - Started to add wireless extensions, but still needs some coding
+ *    - Added watchdog for better handling of transmission timeouts 
+ *      (hopefully this works better)

From 133d7c6a504c672011ebc24b26e05b15f7410c07 Mon Sep 17 00:00:00 2001
From: "John W. Linville" <linville@tuxdriver.com>
Date: Wed, 28 Oct 2009 16:29:30 -0400
Subject: wireless: remove WLAN_80211 and WLAN_PRE80211 from Kconfig

With the WLAN_PRE80211 drivers moved to drivers/staging, this
distinction becomes unnecessary.

Subject: ath9k_hw: update register initialization/reset values for ar9271

This update the register initialization/reset values (aka initvals)
for ar9271 based on the last recommended values on 2009-06-04 by our
systems engineering team.

The changes account for:

  * Supporting ar9271 1.0 and ar9271 1.1 together, the difference
    is bb_spectral_scan_ena, for 1.0 we'll set this to 0x1.

  * Ensuring we get the correct noise floor values -115 ~ -118
    when we enable bb_enable_ant_div_lnadiv=0 and
    mc_tx_def_ant_sel=1. Previous to this we would get noise
    floor values in the range -50 ~ -80. To fix settings for
    the registers:

     - bb_ch1_xatten1_db
     - bb_ch1_xatten2_db
     - bb_ch1_xatten1_margin
     - bb_ch1_xatten2_margin
     - bb_ch1_gain_force
     - bb_ch1_xatten2_hyst_margin
     - bb_ch1_xatten1_hyst_margin
     - bb_ch1_max_oc_gain

  * 0x8120[2] mc_mic_new_location_enable is changed to 0x1. The MAC team
    suggest to set this value.

  * 0x9910[0] bb_spectral_scan_ena is changed to 0x0.
    For ar9271 1.1 we don't need to enable this bit.

Subject: ath9k_hw: change the way we initialize the pll for ar9271

We adjust the core clock for ar9271 to 117 MHz; this also
requires us to adjust the baud divider based on the targetted

Subject: ath9k_hw: start documenting 802.11n RF anlong front ends

Document what we can about the RF analog front ends (radios)
of Atheros 802.11n devices. What should be clearer now is the
what we do for old pre AR5416 and AR5418 MAC based devices in
comparison to the modern sigle-chip 802.11n solutions.

All devices after AR9280 are single chip and require less
programming -- the RF registers no longer need to be initialized
as they all have the RF analog front end embedded together with
the MAC/BB; this includes the AR9271. Older devices such as the
ones with the AR5416 MACs (PCI) or AR5418 MACs (PCI-E) have an
external 2.4 GHz AR2133 radio or a dual band 2.4 GHz / 5 GHz
AR5133 radio. These external radios require additional programming
of the RF registers.

Clarify which parts are for what devices and which code is
shared. This patch has no functional changes.

Subject: ath9k_hw: bail out early on ath9k_hw_init_rf()

We a huge branch for old hardware and nothing for newer
hardware. Instead of doing this just bail out early for
newer hardware.

This patch has no functional changes.

Subject: ath9k_hw: simplify rf attach and rename to
 ath9k_hw_rf_alloc_ext_banks()

ath9k_hw_rfattach() was just calling a helper and this helper was
doing nothing for single-chip devices, and for non single-chip devices
it is just allocating memory for banks to program the RF registers
at a later time. Simplify this by having the hw initialization call
the rf bank allocation directly for external radios.

Also, propagate an -ENOMEM properly now upon failure.

Subject: ath9k_hw: order phy.c code and integrate spur mitigation

This reorders phy.c routines in the order in the order in which they are used
and also moves the spur mitigation helpers for each type of chip into phy.c
as they are RF related.

This patch has no functional changes.

Subject: ath9k_hw: Fix and complete force bias for AR5416

Force bias is a fix for usage of AR5416 radios on the 2.4 GHz band
for orientation sensitivity. This was only partially implemented
with the ath9k_hw_decrease_chain_power() but first -- this was being
called for all chipsets which is not correct and second -- it was
missing the actual orientation code.

We now ensure to only enable force bias only for AR5416 and BUG_ON()
on other chipsets. Although ath9k_hw_decrease_chain_power() was enabled
for newer chipsets I suspect that it never ran unless the EEPROM had
ATH9K_ANT_FIXED_A or ATH9K_ANT_FIXED_B for antenna diversity.

Subject: wl1271: fix init loop timeout

The check after the loop which checks whether the initialization timed-out
was wrong.  If the initialization would succeed exactly in the 20000th time
(the value set for INIT_LOOP), the driver would bail out and claim that
initialization failed.

Use dev_get_by_name_rcu() instead of dev_get_by_name(),
to avoid touching device refcount in hotpath.

Subject: libertas: remove internal buffers from GSPI driver

This patch removes the internal command and data buffers that the GSPI driver
maintained and instead relies on the Libertas core to synchronize access
to the command and data ports as with the other interface drivers.  This
cleanup reduces the GSPI driver's memory footprint and should improve
performance by removing the need to copy to these internal buffers.
This also simplifies the bottom half of the interrupt handler.

This is an incremental cleanup: after removing the redundant buffers, we
can further improve the driver to use a threaded IRQ handler instead of
maintaining its own thread.  However I would like a few folks to test
the buffer removal first and make sure that I'm not introducing
regressions.

Tested on Blackfin BF527 with DMA disabled due to an issue with the SPI
host controller driver in the current bleeding-edge Blackfin kernel.  I
would appreciate it if someone with working DMA could test this patch
and provide feedback.

Subject: iwlwifi: remove unneeded locks from apm_stop() and stop_master()

Since priv->reg_lock was added to keep multi-access register manipulation
atomic, priv->lock protection is no longer needed.  Remove this from
iwl_apm_stop_master() and iwl_apm_stop().

Add warning of timeout when polling for busmaster disablement confirmation,
and some comments.

NOTE:  This is needed to enable use of apm_ops.stop() within iwl_eeprom_init();
priv->lock does not get initialized until after this flow.  See patch
"remove power-wasting calls to apm_ops.init()"

Subject: iwlwifi: remove power-wasting calls to apm_ops.init()

To save power, don't run apm_ops.init() until needed at "up" time.

EEPROM (5000 and earlier devices) may be read without running apm_ops.init(),
but OTP reads (6000 and newer devices) require a powered-up chip.
Therefore, remove apm_ops.init() from the general path in XXXX_pci_probe(),
and call it only if device uses OTP.  Once done with OTP read, call
apm_ops.stop() to reset chip and save power until "up" time comes around.

NOTE:  This patch depends on removal of priv->lock from iwl_apm_stop();
lock does not get initialized until later in flow.  See patch
"remove unneeded locks from apm_stop()".

Subject: iwlagn: invoke L0S workaround for 6000/1000 series

Invoke workaround to avoid instability in L0->L0S->L1 transition on PCIe bus.
Workaround disables L0S state so device moves directly from L0->L1.
Workaround needed on all devices since and including 4965; add to 6000/1000.

Describe bug and workaround better in comments.

Subject: iwlagn: update write pointers for all tx queues after wakeup

Wakeup interrupt has been updating write pointers (indexes, actually) only
for tx queues 0-5.  This is adequate just for 3945, but inadequate for other
devices, all of which have more tx queues.  Now updating all tx/command queues,
so device can be aware of all new tx and host commands enqueued while
device was asleep.

This can potentially improve data traffic bandwidth and/or latency.

Subject: iwlwifi: unmap memory before use

Handling responses to driver originated commands include passing the
original command buffer to the caller. At this time it is possible for a
callback to be invoked that is passed this command buffer and thus likely
to access it.

We need to make sure that the memory associated with that buffer is not DMA
mapped at the time.

Subject: iwlwifi: move iwl_[un]init_drv to iwlagn

Since iwlagn is the only user of these functions, move it to this module.
This results in a bit more code moving than just these functions since the
functions only used by them are also moved and we need to export the
symbols previously available to them directly.

Subject: iwlwifi: split adding broadcast station from others

In preparation for some station management changes we split the addition of
a broadcast station from the other stations. Later we will rely on mac80211
to direct all management (addition/removal) of all stations except the
broadcast station.

Subject: iwl3945: store station rate scale information in mac80211 station
 structure

Currently the rate scale information is pointed to from the mac80211
station structure but since that is the only member we might as well make
it part of the structure. Also move the rate scaling initialization to the
init function, no need to do it when we allocate the structure. This fits
with how mac80211 deals with rate scaling information (it always calls init
after allocation) and makes it easier for us to later call initialization
directly.

Subject: iwlagn: move rate scale initialization to init function

This fits better in how the callbacks operate (alloc does allocation and
init does initialization). This also helps if we later want to do our own
initialization without relying on the mac80211 allocation.

Subject: iwlwifi: add SM PS support for 6x50 series

Spatial Multiplexing Power Save was disabled to achieve better
throughput while in power save mode by activating all the rx chains all the time.
By doing so, the device power consumption is high.

Enable static/dynamic spatial multiplexing power save if device support
it, which can lower the power consumption without impact throughput.

Subject: iwlwifi: add wimax/wifi coexist support for 6x50 series

For 6x50 series, it is wimax/wifi combo device, so driver need to enable
the wimax/wifi co-exist function and send the coexist event priority
table to uCode for operation.

The priority table will be used by uCode to determine what is the proper
action it should take when co-exist with WiMAX.
For example, when WiFi runs a scan, it must own radio exclusively, therefore
will disconnect WiMAX if WiMAX is connected.

messages instead of preventing the mayhem from happening.

the reason is that "p54: generate channel list dynamically"
is not perfect. It didn't discard incomplete channel data
sets and therefore p54 advertised to support them as well.

Track the idle state for hwsim radios and reject TX if mac80211 is
trying to transmit something when the radio is supposed to be idle. In
addition, do not deliver frames if the receiving radio is in the idle
state.

current AP only, so it needs to be updated only when the BSSID changes.

Removed excess setting of the template.

Currently, to avoid distortions, the TX power level has been hardcoded
to a low value. The value is slightly too low for good functionality, so
we increase it from 7dB to 12dB.

PSM entries can fail (transmitting the corresponding null-func may not

out-of-sync between STA and AP could occur.

Add retry implementation for the entries to recover from the situation.

Subject: tg3: Fix 5906 transmit hangs

The 5906 has trouble with fragments that are less than 8 bytes in size.
This patch works around the problem by pivoting the 5906's transmit
routine to tg3_start_xmit_dma_bug() and introducing a new SHORT_DMA_BUG
flag that enables code to detect and react to the problematic condition.

Subject: tg3: Convert PHY_ADDR => TG3_PHY_MII_ADDR

This patch renames the PHY_ADDR preprocessor definition.  The following
patch will identify a new member on the MDIO bus, so we want this
preprocessor definition to be a little more descriptive.

Subject: tg3: Add more PCI DMA map error checking

This patch adds code to check the status of pci_map_single() before
allowing rx buffers to be used.  It also converts the pci_map_single()
call in tg3_run_loopback() to use skb_dma_map() instead.

Subject: tg3: Add AC131 power down support

The AC131 does not respect the power down bit (bit 11) of the MII
Control Register (reg 0x0).  Instead, software is required to put the
phy into standby power down mode through the shadow register set.  This
patch implements support for the AC131 standby power down mode.

This patch extends the loopback test timeout from 250 usec to 350 usec.
When the 5785 is paired against an AC131 phy, the older timeout is
just a little too close to the expected performance based on timings.

Subject: tg3 / broadcom: Add PHY_BRCM_CLEAR_RGMII_MODE flag

Broadcom 50610M parts changed the default definitions of the RGMII mode
shadow register.  The 5785 needs the RGMII mode selection bits [4:3]
cleared.

The default value of the remaining bits in this register are zero.
Rather than unnecessarily burn an extra bit in the dev_flags member in
an attempt to enumerate all possible combinations, this patch take a
more course grained approach and labels the option as "clear all bits".

Auto power-down (APD) support is a power-saving feature.  It should be
selectively enabled since it might expose MAC bugs.  This patch changes
the code to enable APD only if the PHY_BRCM_AUTO_PWRDWN_ENABLE flag is
set.  The tg3 driver was changed to set this bit.

Subject: tg3 / broadcom: Add code to disable rxc refclk

The 5785 does not use the RXC reference clock.  Turning it off is
desirable as it saves power.

By default, the 50610 enables the RXC reference clock and the 50610M
disables it.  Presumably this is one of the reasons why the hardware
architect chose one over the other.

Adding a "rx reference clock disable" flag is not the ideal way to
describe the option, as it would force the MAC using a 50610M to set
the flag.  Ideally we want the flags to represent opt-in behavior that
deviates from hardware defaults.  Furthermore, the lack of a
"disable" flag implies that the requester wants the rx reference clock
enabled, which doesn't necessarily follow.

By presenting the option as a passive statement (rx reference clock
unused) rather than a command, I hope to convey an opt-in option to
disable the rx reference clock that falls back to hardware defaults if
not set.  A secondary benefit of this is that it keeps the
intelligence about phy defaults in the broadcom module where it belongs
and allows the broadcom module more latitude should a bug arise.

Subject: gianfar: Add per queue structure support

This patch introduces per tx and per rx queue structures.
Earlier the members of these structures were inside the
gfar_private structure.

Moving forward if we want to support multiple queues, we need
to refactor the gfar_private structure so that introduction of
multiple queues is easier.

From f4983704a63b3764418905a77d48105a8cbce97f Mon Sep 17 00:00:00 2001
From: Sandeep Gopalpet <Sandeep.Kumar@freescale.com>
Date: Mon, 2 Nov 2009 07:03:09 +0000
Subject: gianfar: Introduce logical group support.

This patch introduces the group structure. The elements of this
structure are the interrupt lines, their corresponding names,
the register memory map.
The elements for this group are factored out from the gfar_private
structure. The introduction of group structure will help in
providing support for newer versions of etsec.

Currently, the support is present only for single group and
single tx/rx queues.

From fba4ed030cfae7efdb6b79a57b0c5a9d72c9de83 Mon Sep 17 00:00:00 2001
From: Sandeep Gopalpet <Sandeep.Kumar@freescale.com>
Date: Mon, 2 Nov 2009 07:03:15 +0000
Subject: gianfar: Add Multiple Queue Support

This patch introduces multiple Tx and Rx queues.
The incoming packets can be classified into different queues
based on filer rules (out of scope of this patch). The number
of queues enabled will be based on a DTS entries fsl,num_tx_queues
and fsl,num_rx_queues.

Although we are enabling multiple queues, the interrupt coalescing
is on per device level (etsec-1.7 doesn't support multiple rxics
and txics).

From 46ceb60ca80fa07703bc6eb8f4651f900dff5a82 Mon Sep 17 00:00:00 2001

Subject: gianfar: Add Multiple group Support

This patch introduces multiple group support for etsec2.0
devices.

Multiple group support is provided by mapping the set of enabled
queues to different groups and then programming the per group
regsiters imask, ievent, rstat, tstat.

The queues corresponding to a group are indicated by programming
isrg (interrupt steering) registers.

Subject: wimax/i2400m: implement passive mode as a module option

Some versions of the user space Intel WiMAX daemon need to have full
control over the device initialization sequence. By setting the module
option i2400.passive_mode to 1, the driver defers all device
configuration and initialization to user space.

Subject: wimax/i2400m: introduce i2400m_reset(), stopping TX and carrier

Currently the i2400m driver was resetting by just calling
i2400m->bus_reset(). However, this was missing stopping the TX queue
and downing the carrier. This was causing, for the corner case of the
driver reseting a device that refuses to go out of idle mode, that a
few packets would be queued and more than one reset would go through,
making the recovery a wee bit messy.

To avoid introducing the same cleanup in all the bus-specific driver,
introduced a i2400m_reset() function that takes care of house cleaning
and then calling the bus-level reset implementation.

The bulk of the changes in all files are just to rename the call from
i2400m->bus_reset() to i2400m_reset().

Subject: wimax/i2400m: fix device getting stuck in IDLE mode

The i2400m, when conected, will negotiate with the WiMAX basestation
to put the link in IDLE mode when it is not being used. Upon RX/TX
traffic, the link has to be restablished and that might require some
crypto handshakes and maybe a DHCP renew.

This process might take up to 20 (!) seconds and in some cases we were
seeing network watchdog warnings that weren't needed.

So the network watchdog timeout is updated to be slightly above that
20s threshold. As well, the driver itself will double check if the
device is stuck in IDLE mode -- if that happens, the device will be
reset (in this case the queue is also woken up to remove bogus--once
the device is reset--warnings).

Subject: wimax/i2400m: Fix USB timeout specifications (to ms from HZ)

The USB code was incorrectly specifiying timeouts to be in jiffies vs
msecs. On top of that, lower it to 200ms, as 1s is really too long
(doesn't allow the watchdog to trip a reset if the device timesout too
often).

Subject: wimax/i2400m: correctly identify all iwmc3200-based SKUs

Different paths of the i2400m SDIO driver need to take care of a few
SKU-specific quirks. For the ones that are common to to all the
iwmc3200 based devices, introduce i2400ms->iwmc3200 [set in
i2400ms_probe()], so it doesn't have to check against the list of
iwmc3200 SKU IDs on each quirk site.

Subject: wimax/i2400m: don't retry SDIO enable in probe() paths

The iwmc3200 has a quirk where retrying SDIO enable during the probe()
path causes bad interactions with the TOP function controller that
causes a reset storm. The workaround is simply not to retry an SDIO
enable in said path (and still do in the reset / reinitialization
paths).

The driver does so by checking i2400ms->debugfs_dentry to see if it
has been initialized; if not, it is in the probe() path. Document said
fact in i2400ms->debugfs_entry.

Subject: wimax/i2400m: handle USB stalls

When the device stalls, clear it and retry; if it keeps failing too
often, reset the device.

This specially happens when running on virtual machines; the real
hardware doesn't seem to trip on stalls too much, except for a few
reports in the mailing list (still to be confirmed this is the cause,
although it seems likely.

NOTE: it is not clear if the URB has to be resubmitted fully or start
only at the offset of the first transaction sent. Can't find
documentation to clarify one end or the other.

Tests that just resubmit the whole URB seemed to work in my
environment.

Subject: mwl8k: fix GET_STAT firmware command packet layout

The GET_STAT command doesn't have an 'action' field like other
commands do, so remove it.

From 88de754ad59025eba797e7a8375807755577f450 Mon Sep 17 00:00:00 2001
From: Lennert Buytenhek <buytenh@wantstofly.org>
Date: Thu, 22 Oct 2009 20:19:37 +0200
Subject: mwl8k: minor transmit quiescing rework

Minor changes to the transmit quiescing logic:
- Clarify the locking rules for ->tx_wait: only the holder of fw_mutex
  can wait for the TX path to become idle, but tx_wait itself is read
  and cleared by the TX reclaim tasklet under tx_lock.
- Inline mwl8k_txq_busy() in its callers.
- There's no need to kick the transmitter again in
  mwl8k_tx_wait_empty(), since it will have been kicked when the
  packets currently in the TX ring were added to it.
- If the TX ring didn't drain in time, run mwl8k_scan_tx_ring() after
  reading priv->pending_pkts without dropping tx_lock in between.

Subject: mwl8k: fix multicast address filter programming

mwl8k's ->prepare_multicast() currently just enables reception of
all multicast packets, which is somewhat ineffective.

Fix this by either disabling all multicast RX, enabling multicast
RX according to the multicast address filter table, or enabling all
multicast RX, depending on whether ->prepare_multicast() was given
any multicast addresses and whether the hardware multicast address
filter table is large enough to fit all requested addresses.

Subject: mwl8k: enforce FIF_BCN_PRBRESP_PROMISC when no STA interfaces are
 active

When FIF_BCN_PRBRESP_PROMISC is not set, we enable the hardware's BSS
filter so that we'll only see packets destined for our BSS.  But if no
STA interfaces have been configured, we would end up passing the BSSID
00:00:00:00:00:00 into the POST_SCAN command, which actually disables
the hardware's BSS filter, as it's not a valid BSSID.

Fix this by passing in 01:00:00:00:00:00 instead (the criterion is
that the OUI part of the BSSID must be nonzero), and add comments to
explain what PRE_SCAN and POST_SCAN do.

Subject: mwl8k: use cond_resched() when loading firmware blocks

Since each firmware block takes on the order of several hundred usec
to upload to the hardware, using msleep in the inner loop would make
the firmware loading process take a lot more time than just doing
busy-waiting like we do now.  But if we keep the busy-waiting, we can
at least add a cond_resched() to the inner loop so that we give other
tasks a chance to run while the firmware is being loaded.

Subject: mwl8k: pci BAR mapping changes

Map BAR0 as well, as we need to write to it during init on some chips.

Also, if BAR0 is a 64bit BAR, the register BAR becomes BAR2, so try
mapping BAR2 if mapping BAR1 fails.

Subject: mac80211: make ieee80211_find_sta per virtual interface

Since we have a TODO item to make all station
management dependent on virtual interfaces, I
figured I'd start with pushing such a change
to drivers before more drivers start using the
ieee80211_find_sta() API with a hw pointer and
cause us grief later on.

For now continue exporting the old API in form
of ieee80211_find_sta_by_hw(), but discourage
its use strongly.

Subject: rt2800usb: use rt2x00usb_register_multiwrite() to set key entries

Since struct hw_key_entry is 32-bytes large and is smaller than
CSR cache size (which is 64-bytes large) we can use the standard
rt2x00usb_register_multiwrite() helper to set key entries.

This cleanup is a part of preparations for later code unification.

From 7846e471b5b5cac5e09c8e6ebeb67e18279db8e3 Mon Sep 17 00:00:00 2001
From: Yaniv Rosner <yanivr@broadcom.com>

Subject: bnx2x: Fix CL73 autoneg issues

- Advertise 1G KX4 in CL73 when 1G speed capability is enabled
- Add flow-control negotiation over CL73
- External loopback test on Serdes should be done in FORCE mode, since in
CL73 it is unable to link up with the same core using AUTONEG
- Fix bnx2x_set_led function to support CL73 link leds

Subject: bnx2x: Enable FC when parallel-detect is used

When parallel detect is used, flow-control is set to the
req_fc_auto_adv instead of none.

Motive: when 577xx is FC configuration is set to AUTO, while LP speed
is set to FORCE mode and FC to force RX/TX, link would come up using
parallel detect, and the FC will be set to NONE since FC capabilities
were not negotiated, although the LP is setting FC to force RX/TX.

Subject: bnx2x: Fix register access timeout in 10M

In BCM8481 when link speed goes from 1G to 10M, driver received timeout
since the MAC clock hasn't synced yet with the new speed, so it is required
first to program the MAC with the new speed, and only then configure other
parameters

Subject: net: pass kern to net_proto_family create function

The generic __sock_create function has a kern argument which allows the
security system to make decisions based on if a socket is being created by
the kernel or by userspace.  This patch passes that flag to the
net_proto_family specific create function, so it can do the same thing.

Subject: rt2x00: add driver private field to struct rt2x00_dev

Enhance rt2x00 infrastructure by adding driver specific field to
struct rt2x00_dev.

The new field will be used by rt2800 drivers for chipset registers
access abstraction layer.

Subject: rt2x00: fix rt2x00pci_register_multi[read,write]() arguments

Change type of 'length' argument from u16 to u32 (all arguments
match rt2x00usb_register_multi[read,write]() ones now).

Subject: rt2800usb: add RXINFO_DESC_SIZE definition

Add RXINFO_DESC_SIZE definition and use it instead of abusing
RXD_DESC_SIZE one (TXD_DESC_SIZE and RXD_DESC_SIZE are specific
to PCI version of the chipset).

Subject: rt2x00: add support for different chipset interfaces

Enhance rt2x00 infrastructure by adding explicit information
about used chipset interface to struct rt2x00_chip.

The new field will be used by rt2800 drivers for rt2800 library.

Also add commonly used rt2x00_intf_is_pci() and rt2x00_intf_is_usb()
helpers to make code easier to read (noticed by Ivo van Doorn).

Subject: mwl8k: change pci id table driver data to a structure pointer

To prepare for adding support for more device types, introduce a
new structure, mwl8k_device_info, where per-device information can
be stored, and change the pci id table driver data from an integer
indicating only the part number to a pointer to a mwl8k_device_info
structure.

AP and STA firmware images provide a different signature in the
HIU_INT_CODE register after loading.  Record which of the signatures
we saw, as it determines which command sequences to use later on.

Subject: mwl8k: allow for different receive descriptor formats

As the receive descriptor format is determined by the firmware running
on the hardware and not by the hardware itself, and as these
descriptor formats vary a bit between different firmware releases,
abstract out the receive descriptor init/refill/process methods, and
allow choosing between different formats at run time depending on the
chip and firmware we're running on.

Subject: mwl8k: use integral index instead of pointer for driver_data

Use of an integral index makes adding new device IDs through sysfs more
practical.

Subject: net/tun: handle compat_ioctl directly

The tun driver is the only code in the kernel that operates
on a character device with struct ifreq. Change the driver
to handle the conversion itself so we can contain the
remaining ifreq handling in the socket layer.

This also fixes a bug in the handling of invalid ioctl
numbers on an unbound tun device. The driver treats this
as a TUNSETIFF in native mode, but there is no way for
the generic compat_ioctl() function to emulate this
behaviour. Possibly the driver was only doing this
accidentally anyway, but if any code relies on this
misfeature, it now also works in compat mode.

Subject: net, compat_ioctl: handle socket ioctl abuses in tty drivers

Slip and a few other drivers use the same ioctl numbers on
tty devices that are normally meant for sockets. This causes
problems with our compat_ioctl handling that tries to convert
the data structures in a different format.

Fortunately, these five drivers all use 32 bit compatible
data structures in the ioctl numbers, so we can just add
a trivial compat_ioctl conversion function to each of them.

SIOCSIFENCAP and SIOCGIFENCAP do not need to live in
fs/compat_ioctl.c after this any more, and they are not
used on any sockets.

Subject: fsl_pq_mdio: Fix compiler/sparse warnings (part 1)

commit 1d2397d742b7a2b39b2f09dd9da3b9d1463f55e9 ("fsl_pq_mdio: Add
Suport for etsec2.0 devices") introduced the following warnings:

  CHECK   fsl_pq_mdio.c
fsl_pq_mdio.c:287:22: warning: incorrect type in initializer (different base types)
fsl_pq_mdio.c:287:22:    expected unknown type 11 const *__mptr

fsl_pq_mdio.c:287: warning: initialization makes pointer from integer without a cast
fsl_pq_mdio.c:287: warning: assignment makes integer from pointer without a cast

These warnings are not easy to fix without ugly __force casts. So,
instead of introducing the casts, rework the code to substitute an
offset from an already mapped area. This makes the code a lot simpler
and less duplicated.

Plus, from now on we don't actually map reserved registers on
non-etsec2.0 devices, so we have more chances to catch programming
errors.

Subject: fsl_pq_mdio: Fix compiler/sparse warnings (part 2)

This patch fixes following warnings:

fsl_pq_mdio.c:124:38: warning: cast adds address space to expression (<asn:2>)
fsl_pq_mdio.c:133:38: warning: cast adds address space to expression (<asn:2>)
fsl_pq_mdio.c:414:11: warning: cast adds address space to expression (<asn:2>)

Instead of adding __force all over the place, introduce convenient
fsl_pq_mdio_get_regs() call that does the ugly casting just once.

Subject: net: Support specifying the network namespace upon device creation.

There is no good reason to not support userspace specifying the
network namespace during device creation, and it makes it easier
to create a network device and pass it to a child network namespace
with a well known name.

We have to be careful to ensure that the target network namespace
for the new device exists through the life of the call.  To keep
that logic clear I have factored out the network namespace grabbing
logic into rtnl_link_get_net.

In addtion we need to continue to pass the source network namespace
to the rtnl_link_ops.newlink method so that we can find the base
device source network namespace.

Some usbnet drivers update link state while others do not due to
hardware limitations.  Add a flag to distinguish those that do, and
set the link down initially for their devices.

This is intended to fix this bug: http://bugs.debian.org/444043

Allocate 128 bytes linear buffer for rx skb. The first 64 bytes is
reserved for mac80211 usage (for radiotap header expansion, etc).
The frame header starts from the second 64 bytes.

Subject: iwlwifi: don't double-activate queue 4

The fourth queue (command queue) is already activated in
the loop above that also maps it to the command FIFO and
therefore doesn't need to be marked as activated again.
Also change the TODO comment to be accurate -- we need
to initialise the _queues_, not FIFOs, and map them to
device FIFOs.

Subject: iwlwifi: fix FIFO vs. queue confusion

When I added that code setting the swq_id, I evidently
did not understand the distinction between FIFO and TX
queue yet and added code to compare a queue ID and a
FIFO number, which is bogus.

However, the code there need not be this specific, it
can just set all queues to the identity mapping which
will be overwritten by the aggregation queue code. As
a bit of defensive coding, don't assign an swq_id to
the command queue so that if we ever use it for frames
we notice quickly.

Subject: iwlwifi: fix for channel switch

Different channel has different configuration, need to pass correct
configuration to uCode when send "channel switch" command to uCode.
Invalid configuration will cause sysassert in uCode and produce
un-expected result.

Even it is a very small windows, but we also need to consider and handle
the case if commit_rxon occurred before the "channel switch
announcement" notification received from uCode.

Subject: iwlwifi: Limit size of Event Log dump

If device provides bad values for Event Log parameters (due to being asleep
or SRAM corruption, etc.), the size can be very, very large (e.g. 0xa5a5a5a5),
which can flood system log.

Sanity-check capacity and next_entry values and limit to reasonable size dump.

Subject: iwlwifi: speed up event log dumps

Take advantage of device's auto-increment for SRAM reads to eliminate extra
write address accesses.

Grab/release NIC access before/after entire read sequence, rather than for
each read individually.

After a quick check of dmesg logs, this seems to double Event Log dump speed,
reducing from about 20 milliseconds to about 10 milliseconds for 512 entries
using 3945.

Subject: iwlagn: update write pointers in iwl_irq_tasklet()

Follow-up to "update write pointers for all tx queues after wakeup"; that
patch changed iwl_irq_tasklet_legacy(), but not iwl_irq_tasklet(), so
newer devices were not covered.

Comments from original patch:

Wakeup interrupt has been updating write pointers (indexes, actually) only
for tx queues 0-5.  This is adequate just for 3945, but inadequate for other
devices, all of which have more tx queues.  Now updating all tx/command queues,
so device can be aware of all new tx and host commands enqueued while
device was asleep.

This can potentially improve data traffic bandwidth and/or latency.

Subject: iwlwifi: MAC_ACCESS_REQ cleanup

Add txq_id info to "Tx queue requesting wakeup" debug message

Add "Rx queue requesting wakeup" debug message

Move clear of CSR_GP_CNTRL_REG_FLAG_MAC_ACCESS_REQ to be after nearby
iwl_write_prph(), since iwl_write_prph() sets it and clears it.  Almost
removed it entirely, but just making sure in case someone removes the
iwl_write_prph()!  Also remove unneeded priv->lock usage; this is now
handled by priv->reg_lock within iwl_clear_bit().

Join a couple of lines that had unneeded line returns.

Subject: drivers/net/wireless: correct check on CCS_START_NETWORK

CCS_START_NETWORK is declared in drivers/net/wireless/rayctl.h with the
comment Values for cmd.  status is previously compared to
CCS_COMMAND_COMPLETE, which is declared in the same file with the comment
Values for buffer_status.  Finally, it is possible at this point that cmd
is CCS_START_NETWORK, because it is compared to that value in an enclosing
switch that has CCS_START_NETWORK as one of two case labels around this code.

Subject: rt2x00: Fix building of rt2800lib when rt2x00 driver is built-in.

When enabling rt2800usb as a built-in driver (as opposed to a as a module) the build fails. See
http://marc.info/?l=linux-wireless&m=125768687711034&w=2 for details.

Fix it by properly including <linux/usb.h> from rt2x00usb.h

Subject: ath9k: fix listening to idle requests

The way idle configuration detection was implemented as
busted due to the fact that it assumed the ath9k virtual wiphy,
the aphy, would be marked as inactive if it was not used but
it turns out an aphy is always active if its the only wiphy
present. We need to distinguish between aphy activity and
idleness so we now add an idle bool for the aphy and mark
it as such based on the passed IEEE80211_CONF_CHANGE_IDLE
from mac80211.

Previous to all_wiphys_idle would never be true when using
only one device so we never really were using
IEEE80211_CONF_CHANGE_IDLE -- we never turned the radio
off or on upon IEEE80211_CONF_CHANGE_IDLE changes as radio
changes depended on all_wiphys_idle being true either to
turn the radio on or off. Since it was always false for
one device this code was doing nothing.

Subject: ath9k: update hw configuration for virtual wiphys

ath9k supports its own virtual wiphys. The hardware code
relies on the ieee80211_hw for the present interface but
with recent changes introduced the common->hw was never
updated and is required for virtual wiphys.

Subject: ath9k: use the passed ieee80211_hw on ath_rx_prepare()

this now uses the proper hw which should mean finding the
right sta when using ath9k virtual wiphy stuff. Only
advantage I see here is getting the rssi properly updated
so the 'fix' itself isn't that great, but at least this
is correct.

Subject: ath9k: pass the ieee80211_hw on radio enable/disable

We use the ieee80211_hw for radio enable/disable but the wrong
structure hw was being used in consideration for virtual wiphys
as each virtual wiphy has its own ieee80211_hw struct.

Just pass the hw struct to ensure we use the right one. This should
fix the hw used and passed for radio enable/disable. This includes
the stoping / starting of the software TX queues so mac80211 doesn't
send us data for a specific virtual wiphy. ath9k already takes care
of pausing virtual wiphys and stopping the respective queues on its
own, but this should handle the idle mac80211 conf calls as well.

Subject: ath9k: use correct hw for tx aggregation TX completion

When ath9k virtual wiphys are used the sc->hw will not always represent
the active hw, instead we need to get it from the skb->cb private
driver area. This ensures the right hw is used to find a sta for
the TX'd skb.

Subject: ath9k: handle low buffer space for virtual wiphys

ath9k virtual wiphys all share the same internal buffer space
for TX but they do not share the mac80211 skb queues. When
ath9k detects it is running low on buffer space to TX it tells
mac80211 to stop sending it skbs its way but it always does
this only for the primary wiphy. This means mac80211 won't know
its best to avoid sending ath9k more skbs on a separate virtual
wiphy. The same issue is present for reliving the skb queue.

Since ath9k does not keep track of which virtual wiphy is hammering
on TX silence all wiphy's TX when we're low on buffer space. When
we're free on buffer space only bother informing the virtual wiphy
which is active that we have free buffers.

Subject: ath9k: do not pass the entire descriptor to ath_rx_prepare()

Its not needed, so just pass the hardware RX status.
We'll be simplfying ath_rx_prepare() with code we can share
between ath9k and ath9k_htc. This will help make that code
easier to read and manage.

Subject: ath9k: use the ieee80211_hw to get to an sband on ath_rx_prepare()

No need to use the private driver structure to get to an sband.
This will make it easier to share this code with ath9k_htc.

With the sc gone we can now just pass the common structure to
ath_rx_prepare().

Subject: ath9k: avoid the copy skb->cb on every RX'd skb

The skb->cb (control buffer, 48 bytes) is available to the skb
upon skb allocation. You can fill it up imediately after skb
allocation. ath9k was copying onto the skb->cb the data from the
processed skb for mac80211 from a stack struct ieee80211_rx_status
structure. This is unnecessary, instead use the skb->cb for the
rx status immediately after the skb becomes available and DMA
synched.

Additionally, avoid the copy of the skb->cb also for virtual wiphys
as skb_copy() will copy over the skb->cb for us as well.

Subject: ath5k: remove double cache alignment, ath_rxbuf_alloc() already does
 it

ath5k is using the (csz - 1) twice as ath_rxbuf_alloc() already allocates
and moves skb->data accordingly. Remove the extra (csz -1).

Subject: ath9k_common: add new module to share 802.11n driver helpers

ath9k and ath9k_htc share a lot of common hardware characteristics.
They only differ in that ath9k_htc works with a target CPU and ath9k
works directly with the hardware. ath9k_htc will do *some* things in
the firmware, but a lot of others on the host.

The common 802.11n hardware code is already shared through the ath9k_hw
module. Common helpers amongst all Atheros drivers can use the ath module,
this includes ath5k and ar9170 as users. But there is some common driver
specific helpers which are not exactly hardware code which ath9k and
ath9k_htc can share. We'll be using ath9k_common for this to avoid
bloating the ath module and the common 802.11n hardware module ath9k_hw.

We start by sharing skb pre and post processing in preparation for a hand
off to mac80211.

Subject: ath9k_common: remove ath9k_compute_qual()

This is now deprecated and unused within mac80211, so time
to remove it as otherwise we'd be doing some unecessary
computations for nothing.

Subject: ath9k_common: clarify and correct jumbogram processing

Jumbograms are frames put together linked together through
more than one descriptor. For example ath9k_htc will use this
to send from the target a large frame split up into 2 or more
segments. The driver then would be in charge of putting the
frame back together.

When jumbograms are constructed the rx_stats->rs_more will
bet set and rx_stats->rs_status will not have any valid content
as the actual status will only be avialable at the end of
the chained descriptors.

Instead of assuming that all rt3090 devices will have an eFuse EEPROM,
do as the legacy Ralink driver, and detect at run-time whether an
eFuse EEPROM is present.

Subject: rt2800usb: reorganize code in rt2800usb_probe_hw_mode()

Move hw_mode information initialization code block before
HT information initialization one to match the ordering used
by rt2800pci's rt2800pci_probe_hw_mode().

Subject: rt2800usb: fix RX descriptor naming

Rename RXD_W0_* defines to RXINFO_W0_* ones to match naming
used for TX descriptor and by the vendor driver.

Subject: rt2800: add eFuse EEPROM support code to rt2800lib

eFuse EEPROM is used also by USB chips (i.e. RT3070)
so move the needed code from rt2800pci to rt2800lib.

Subject: rt2500usb: remove dead link tuning code

Link tuning code from the legacy rt2570 driver turned out to be
harmful and got disabled by the commit d06193f ("rt2x00: Disable
link tuning in rt2500usb") in August 2008.

There is no reason to keep this dead code any longer so remove it
(it can still be retrieved from the git history if necessary).

Subject: rt2x00: Update copyright statements.

As mentioned on the linux-wireless mailing list, the current copyright
statements in the rt2x00 are meaningless, as the rt2x00 project is
not even a formal legal entity. Therefore it is better to replace
the existing copyright statements with copyright statements for the
people that actually wrote the code.

Note: Updated to the best of my knowledge with respect to who
contributed considerable amounts of code.

Subject: at76c50x-usb: Supply additional parameters to at76_start_monitor scan
 request

For my Linksys WUSB11 at76c503-i3861 device, scanning fails without
probe_delay, min_channel_time, and max_channel_time specified for the
scan request.  These values were found by checking scan requests from
the at76_usb driver.

gfar_error() can arrive at the middle of gfar_start_xmit() processing,
and so it can trigger transfers of BDs that we don't yet expect to
be transmitted.

Fix this by locking the tx queues in gfar_error().

Subject: gianfar: Revive SKB recycling

Before calling gfar_clean_tx_ring() the driver grabs an irqsave
spinlock, and then tries to recycle skbs. But since
skb_recycle_check() returns 0 with IRQs disabled, we'll never
recycle any skbs.

It appears that gfar_clean_tx_ring() and gfar_start_xmit() are
mostly idependent and can work in parallel, except when they
modify num_txbdfree.

So we can drop the lock from most sections and thus fix the skb
recycling.

Subject: ixgbe: r_idx not used in ixgbe_msix_clean_rx()

The values of r_idx and rx_ring are not used after the last time they
are set in ixgbe_msix_clean_rx(), so they can be removed.

Subject: DM9000: Wake on LAN support

Add support for Wake on LAN (WOL) reception and waking the device up from
this signal via the ethtool interface. Currently we are only supporting
the magic-packet variant of wakeup.

WOL is enabled by specifying a second interrupt resource to the driver
which indicates where the interrupt for the WOL is being signalled. This
then enables the necessary ethtool calls to leave the device in a state
to receive WOL frames when going into suspend.

Both vlan and macvlan devices usually don't use a qdisc and immediately
queue packets to the underlying device. Propagate transmission state of
the underlying device to the upper layers so they can react on congestion
and/or inform the sending process.

Subject: ath9k_hw: Fix AR_GPIO_INPUT_EN_VAL_BT_PRIORITY_BB and its shift value
 in 0x4054

The bit value of AR_GPIO_INPUT_EN_VAL_BT_PRIORITY_BB is wrong, it should
be 0x400 and the number of bits to be right shifted is 10. Having this
wrong value in 0x4054 sometimes affects bt quality on btcoex environment.

Subject: igb: when number of CPUs > 4 combine tx/rx queues to allow more
 queues

This patch makes it so that nics such as 82576 and newer can support more
hardware queues when there are more than 4 cpus by combining a tx/rx queue
pair onto one interrupt so that 8 queue pairs can be supported and thus
allow for more queues.

Subject: igb: Rework how netdev->stats is handled

This patch does some refactoring work that I felt was needed after reviewing
the changes recently submitted relating to the replacement of net_stats with
netdev->stats.

This patch essentially creates two different collections of stats.  The
first handles the adapter specific states and is stored in gstring_stats,
and the second is for netdev specific stats and is stored in
gstring_net_stats.

Subject: igb: check for packets on all tx rings when link is down

We were previously only checking the first tx ring to see if it had any
packets in it when the link when down.  However we should be checking all
of the rings so this patch makes it so that all of the rings are now being
checked.

Subject: ixgbe: Make queue pairs on single MSI-X interrupts

This patch pairs similar-numbered Rx and Tx queues onto a single
MSI-X vector.  For example, Tx queue 0 and Rx queue 0's interrupt
with be ethX-RxTx-0.  This allows for more efficient cleanup, since
fewer interrupts will be firing during device operation.  It also
helps with a cleaner CPU affinity for IRQ affinity.

Subject: s390: remove cu3088 layer for lcs and ctcm

The cu3088-driver used as common base for lcs- and ctcm-devices
makes it difficult to assign the appropriate driver to an lcs-device
or a ctcm-device. This patch eliminates the cu3088-driver and thus
the root device "cu3088". Path /sys/devices/cu3088 is replaced with
the pathes /sys/devices/lcs and /sys/devices/ctcm.

Patch is based on a proposal from Cornelia Huck.

Subject: hamradio/mkiss: fix typo in compat_ioctl

My last commit introduced an typo causing the
compat_ioctl function to do nothing useful.
The obvious way for an ioctl function to work
is to look at the command, not the argument first.

This patch avoids reprogramming the RCB NIC addresses for all 5755 and
later devices.  The address is incorrect for 5717 devices and should be
correct by default for all other affected devices.

We need room for another TSO flag and it would be most efficient if it
resided in tg3_flags2.  This patch moves the TG3_FLG2_PROTECTED_NVRAM
to tg3_flags3 to make room.

Subject: tg3: Refine TSO and MSI discovery

This patch consolidates the TSO capability discovery code into its own
code block.  The code that decides whether or not to allow TSO is then
cleaned up.  Finally, the patch consolidates all MSI and MSIX
capability code into a single code block.

Subject: tg3: Add new HW_TSO_3 flag for 5717

The 5717 sets up TSO slightly differently in the transmit path.  It
looks like this method will be the new way of doing things.  This patch
defines a flag to indicate this.

Subject: tg3: Allow DMAs to cross cacheline boundaries

By default, the 5717 (and future chips) break up PCIe DMA packets across
cacheline boundaries.  This isn't necessary on x86.  This patch
selectively loosens the restriction.

Subject: tg3: Move napi_add calls below tg3_get_invariants

tg3_get_invariants(), among other things, discovers whether or not
the device is MSI-X capable and how many interrupts it supports.
This discovery needs to happen before registering NAPI instances with
netdev.  This patch moves the code block that calls napi_add later in
tg3_init_one() so that tg3_get_invariants() has a chance to run first.

Subject: tg3: Make tg3_alloc_rx_skb() a dst-only operation

This patch removes the source index parameter of tg3_alloc_rx_skb().  A
later patch will make it possible for the source and destination
producer rings to be different.  This patch opts to make
tg3_alloc_rx_skb() a destination-only implementation and move the code
sensitive to the difference elsewhere.

Subject: tg3: Add prodring parameter to tg3_alloc_rx_skb()

This patch changes the tg3_alloc_rx_skb() implementation to accept the
destination producer ring set pointer as a parameter rather than
assuming the source and destination producer rings are the same.

This patch converts the tnapi argument of tg3_alloc_rx_skb() to tp.  The
level of indirection is unnecessary.

Subject: tg3: rename rx_[std|jmb]_ptr

A later patch is going to add consumer indicies for the producer rings.
To keep things readable, this patch renames rx_[std|jmb]_ptr to
rx_[std|jmb]_prod_idx.

This patch changes how the code uses the rx_std_prod_idx member.  In the
following patch, the code will be changed so that it will act just like
a hardware mailbox.  This patch prepares the code so that memory barriers
can be more easily inserted.

Subject: tg3: Create aliases for rx producer mailbox regs

The rx producer mailbox registers are used in several spots in the code.
The addition of TG3_64BIT_REG_LOW makes register references
uncomfortably long.  This patch creates an alias for the standard and
jumbo ring producer index registers to make the code cleaner.

From 2d6682db114cb53bc94991659478756302e6a600 Mon Sep 17 00:00:00 2001
From: Jay Vosburgh <fubar@us.ibm.com>

Subject: bonding: fix 802.3ad standards compliance error

The language of 802.3ad 43.4.9 requires the "recordPDU" function
to, in part, compare the Partner parameter values in a received LACPDU
to the stored Actor values.  If those match, then the Partner's
synchronization state is set to true.

	The current 802.3ad implementation is performing these steps out
of order; first, the synchronization check is done, then the paramters are
checked to see if they match (the synch check being done against a match
check of a prior LACPDU).  This causes delays in establishing aggregators
in some circumstances.

	This patch modifies the 802.3ad code to call __choose_matched,
the function that does the "match" comparisions, as the first step of
__record_pdu, instead of immediately afterwards.  This new behavior is
in compliance with the language of the standard.

	Some additional commentary relating to code vs. standard is also
added.

	Reported by Martin Patterson <martin@gear6.com> who also supplied
the logic of the fix and verified the patch.

Subject: qeth: Exploit Connection Isolation

Isolate data connection to a shared OSA card against other data
connections to the same OSA card. Connectivity between isolated
data connections sharing the same OSA card is therefore possible only
through external network gear (e.g. a router).

Subject: qeth: Recognize return codes of ccw_device_set_online

Setting a qeth device online requires to call function
ccw_device_set_online() for read-, write-, and data-subchannel.
Failures should be detected immediately without an attempt to
invoke follow-on activity qeth_qdio_clear_card().,

In addition, ccw_device_set_online calls are consolidated in
qeth_core_main.c only.

Subject: qeth: rework TSO functions

The maximum TSO size OSA can handle is 15 * PAGE_SIZE. This
patch reduces gso_max_size to this value and adds some sanity
checks and statistics to the TSO implementation.
Since only layer 3 is able to do TSO move all TSO related functions
to the qeth_l3 module.

Subject: rt2x00: Log RT/RF chipset information correctly.

Some drivers (rt2800* most notably) cannot set the RF and RT chipset in
the correct order to have the information logging in rt2x00_set_chip
be correct.
Fix this by decoupling the setting of the chipset information from the
logging of the chipset information so that drivers can determine
themselves when all information is set.

Subject: rt2x00: Fix BUG on rt2800usb when trying to read eFuse EEPROM.

Current tree hits a BUG_ON in rt2x00_regbusy_read, because the eFuse EEPROM
reading code of rt2800lib uses the function without the csr_mutex locked.

Fix this by locking the csr_mutex for the of the EEPROM reading cycly and
using the _lock variants of the register reading and writing functions.

This also introcudes the register_read_lock function pointer in the
rt2800_ops structure.

Subject: rt2800: do not enable tbtt unless we are in a beacon mode

Please be gentle, I'm a fs developer and this is my first foray into drivers, as
I'm tired of building ralinks driver everytime I update my kernel.  Whenever I
load the rt2800pci driver my box bogs down, and a few printk's later I
discovered its because I was getting 10's of thousands of TBTT interrupts a
second.  I discovered this was because we were setting the beacon timer to 0,
which is apparently what TBTT keys off of.  It seems to me that we should only
be enabling TBTT when we are in a beacon transmitting mode, which from what I
can tell is in AD-HOC and other such modes where the mac80211 layer would have
given us a proper beacon_int to set the beacon timer to instead of 0.  So this
is my fix, only enable TBTT if our sync mode is for beacon.  This makes it so my
box doesn't die everytime I load the rt2800pci driver.  Let me know if this is
acceptable, I just learned all these terms about 15 minutes ago via wikipedia,
so I really am not familiar with how this stuff is supposed to work.  Thanks,

Subject: rndis_wlan: handle NL80211_AUTHTYPE_AUTOMATIC

rndis_wlan didn't know about NL80211_AUTHTYPE_AUTOMATIC and simple
setup with 'iwconfig wlan essid no-encrypt' would fail (ENOSUPP).

v2: use NDIS_80211_AUTH_AUTO_SWITCH instead of _OPEN.
    This will make device try shared key auth first, then open.

Subject: ath5k: allow setting txpower to 0

As a holdover from earlier code when we used to set
the power limit to '0' after a reset to configure the
default transmit power, ath5k interprets txpower=0 as
12.5 dBm.  Fix that by just passing 0 through.

This fixes http://bugzilla.kernel.org/show_bug.cgi?id=14567

Subject: KS8695: fix ks8695_rx_irq() bug.

ks8695 rx irq is edge-level. Before arriving at irq handler, the
corresponding status bit has been clear(irq's ack).
So we should not check it after that.

Subject: KS8695: fix ks8695_rx() unreasonable action.

ks8695_rx() will call refill_buffers() for every incoming packet.
Its not necessary. We just need do it after finishing receiving thing.
And the 'RX dma engine' is in the same situation.
This blocks our user space application. The following patch may fix it.

Subject: net: PPP buffer too small for higher speed connections

1. This patch is based on the kernel of 2.6.32-rc7

2. In this patch, we enlarge the out buffer size to optimize the
   upload speed for the ppp connection. Then it can support the upload of
   HSUPA data cards.

From 115924b6bdc7cc6bf7da5b933b09281e1f4e17a9 Mon Sep 17 00:00:00 2001
From: Shreyas Bhatewara <sbhatewara@vmware.com>
Date: Mon, 16 Nov 2009 13:41:33 +0000
Subject: net: Getting rid of the x86 dependency to built vmxnet3

This patch removes config dependency on x86 to build vmxnet3 driver. Thus
the driver can be built on big endian architectures now. Although vmxnet3
is not supported on VMs other than x86 architecture, all this code goes in
to ensure correctness. If the code is not dependent on x86, it should not
assume little endian architecture in any of its operations.

Subject: znet: fix build failure from i82593.h relocation

znet was including "wireless/i82593.h" (which is a bit wierd), and I
missed that when I relocated i82593.h to drivers/staging/wavelan.  Since
I don't have ISA turned-on in my normal .config, I didn't see the build
failures -- mea culpa!

Subject: macvlan: Precise RX stats accounting

With multi queue devices, its possible that several cpus call
macvlan RX routines simultaneously for the same macvlan device.

We update RX stats counter without any locking, so we can
get slightly wrong counters.

One possible fix is to use percpu counters, to get precise
accounting and also get guarantee of no cache line ping pongs
between cpus.

Note: this adds 16 bytes (32 bytes on 64bit arches) of percpu
data per macvlan device.

Subject: iwlwifi: validate enhanced tx power entry

Validate enhanced tx power entry read from EEPROM before applying the
tx power value. Different versions of EEPROM might contain different size
of table; always a good idea to make sure the entry is valid before
applying to the targeted channel.

When issue REPLY_STATISTICS_CMD to uCode, two possible flag
can be set in the configuration flags

bit 0: Clear statistics
       0: Do not clear Statistics counters
       1: Clear to zero Statistics counters

Allow "clear" parameter to be set from the caller.

Add debugfs file to clear the statistics counters to help monitor and
debug the uCode behavior.

Subject: iwl3945: Reset saved POWER_TABLE_CMD in "up"

Power-saving logic will not re-issue a POWER_TABLE_CMD if a new command
matches the prior one.  This can be bad if we re-start the device due to
e.g. uCode error; the new POWER_TABLE_CMD (required to invoke power-saving)
may match the prior POWER_TABLE_CMD issued before the uCode error.

Ensure the POWER_TABLE_CMD is sent to device when uCode is up.

Subject: iwlwifi: eliminate the possible 1/2 dBm tx power loss in 6x00 & 6x50
 series

In both 6x00 and 6x50 series, the enhanced/extended tx power table in
EEPROM is used to set the max. tx power limit.
This new tx power table is in 1/2 dBm format, which creates an issue of
possibility of 1/2 dBm loss when driver set the tx power limit; because
of driver keep track and report the tx power in dBm format.

In order to prevent the 1/2 dBm loss, keep track of the true max tx
power in 1/2 dBm format in driver; do the comparison and adjust the tx
power if needed when send tx power command to uCode.

Subject: iwlagn: power up device before initializing EEPROM

A recent change optimized the power usage by the device by only powering it
up during EEPROM load if it is required (for OTP devices). This change causes
an error on the 1000 series devices during module load.

The error looks as follows:
[ 1624.024524] iwlagn: Intel(R) Wireless WiFi Link AGN driver for Linux, 1.3.27kds

Adding a dump_stack() to where that error is printed shows the following:

We know that the routines in this trace, iwlcore_eeprom_acquire_semaphore
and iwlcore_eeprom_verify_signature, only access CSR registers and thus do
not need the device to be awake if it is EEPROM. But for OTP it is required
for the device to be awake to read these registers. Ensure device is awake
before accessing these registers.

Subject: iwlwifi: fix bugs in beacon configuration

When sending beacon commands to the uCode, we must
inform it of the offset in the beacon frame of the
TIM Element so it can transmit packets from the
correct queue. This functionality is implemented
in iwl_set_beacon_tim().

Fix a bug setting the rate_n_flags for the beacon
packet. First, it should not use the station table's
rate (it's a management frame), and second it needs
to properly configure the TX antennas.

Finally, also, clean up and comment relevant functions.

Subject: iwlwifi: handle unicast PS buffering

Using the new mac80211 functionality, this makes
iwlwifi handle unicast PS buffering correctly.
The device works like this:

 * when a station goes to sleep, the microcode notices
   this and marks the station as asleep
 * when the station is marked asleep, the microcode
   refuses to transmit to the station and rejects all
   frames queued to it with the failure status code
   TX_STATUS_FAIL_DEST_PS (a previous patch handled
   this correctly)
 * when we need to send frames to the station _although_
   it is asleep, we need to tell the ucode how many,
   and this is asynchronous with sending so we cannot
   just send the frames, we need to wait for all other
   frames to be flushed, and then update the counter
   before sending out the poll response frames. This
   is handled partially in the driver and partially in
   mac80211.

In order to do all this correctly, we need to
 * keep track of how many frames are pending for each
   associated client station (avoid doing it for other
   stations to avoid the atomic ops)
 * tell mac80211 that we driver-block the PS status
   while there are still frames pending on the queues,
   and once they are all rejected (due to the dest sta
   being in PS) unblock mac80211

Subject: ath9k: Cleanup bss_info_changed callback

* Remove a code chunk dealing with operating mode changes.
  As noted, all such policy changes are to be done in
  add_interface.

* Remove pointless check for empty BSSID.
  Also, remove mode checks - mac80211 does all the needed checks.

* Handle enabling/disabling beacon transmission properly.

* Handle beacon interval changes for AP mode.
  The original code depended on config_interface() to update
  the HW TSF. Since that callback has been removed, handle
  it properly.

* Remove unneeded code dealing with key/privacy.

* Set the chainmasks to 1x1 for IBSS when the BSSID is set.
  This was happening uncondionally before.

Subject: ath9k: Remove a few unused functions

ATH9K_ANT_VARIABLE is the default diversity control used.
Consequently ath9k_hw_decrease_chain_power() does nothing.
ath9k_hw_setantennaswitch() is unused too.

Also, gbeacon_rate is unused.

Subject: ath9k: Fix bug in initializing chain masks

Check for AR5416 ver 1.0 before calibrating 3 chains
for multi-chain. This is a WAR for calibration
failure.

Subject: mac80211: convert aggregation to operate on vifs/stas

The entire aggregation code currently operates on the
hw pointer and station addresses, but that needs to
change to make stations purely per-vif; As one step
preparing for that make the aggregation code callable
with the station, or by the combination of virtual
interface and station address.

Subject: ar9170: Add support for D-Link DWA 160 A2

At least two revisions of the D-Link DWA 160 exist, called A1 and A2. A1
(USB-ID 07d1:3c10) is already listed in usb.c as D-Link DWA 160A. A2
(USB-ID 07d1:3a09) works if added to ar9170_usb_ids. I didn't do much
testing until now, but I was able to connect to APs using WPA or WEP and
transmit data.

Summary:

* Add model revision number to the comment for D-Link DWA 160 A1 (07d1:3c10)
* Add support for D-Link DWA 160 A2 (07d1:3a09)

Subject: wl1251: Implement delayed entry into ELP mode

Implement (slightly) delayed entry into ELP. This will cure several
problems:
  - It works around a firmware race condition if ELP is entered too fast
    after commands (resulting in ELP timeout -traces)
  - It will reduce the number of sleep-wake cycles between already
    scheduled events such as interrupts and tx, hence improving
    performance (less delay in switching between RX and TX)

Subject: wl1251: allocate space for firmware with vmalloc()

Earlier firmware was stored to a memory area allocated with kmalloc()
but finding a a contiguous area of memory long enough for the firmware is
very difficult in certain cases. better to allocate the memory for firmware
with vmalloc() instead and use a small buffer for DMA transfers.

Thanks to Eero Tamminen for the idea.

This patch increases the number of beacons to be missed before generating
SYNC TIMEOUT event. It increases the beacon timeout period to 500
microseconds, which gives enough time for the firmware to receive probe
response or beacon. Also handled the regain event from firmware once it
receives a probe response or beacon.

Subject: wl1251: Send null data packet with "TODS" bit set

According to IEEE80211 standard all the data packets have to be sent with
TODS bit set. This patch fixes the null data packet format which was sent
without TODS bit set. This should fix many problems associated with
power save. Janne Ylalehto also found this fix in the same time as mine,
for a different bug he was working on.

Subject: b43: Enforce DMA descriptor memory constraints

Enforce all device constraints on the descriptor memory region.

There are several constraints on the descriptor memory, as documented
in the specification. The current code does not enforce them and/or
incorrectly enforces them.

Those constraints are:
- The address limitations on 30/32bit engines, that also apply to
  the skbs.
- The 4k alignment requirement on 30/32bit engines.
- The 8k alignment requirement on 64bit engines.

Subject: mac80211: request TX status where needed

Right now all frames mac80211 hands to the driver
have the IEEE80211_TX_CTL_REQ_TX_STATUS flag set to
request TX status. This isn't really necessary, only
the injected frames need TX status (the latter for
hostapd) so move setting this flag.

The rate control algorithms also need TX status, but
they don't require it.

Also, rt2x00 uses that bit for its own purposes and
seems to require it being set for all frames, but
that can be fixed in rt2x00.

This doesn't really change anything for any drivers
but in the future drivers using hw-rate control may
opt to not report TX status for frames that don't
have the IEEE80211_TX_CTL_REQ_TX_STATUS flag set.

When setting WoL feature, check the supplied modes are all supported rather
than checking for no support.  This way, if any new modes are added the
driver does not default to not complaining about it if we don't really
support it.

Clearing the interrupt timers following an IMS clear has the unwanted

Subject: e1000e: link reporting problems

Copper links with WoL or management enabled (any condition which prevents
the phy from being powered down when the interface is taken down) were
always reporting link-up when the interface had been taken down. This
is because when the interface is taken down (ifconfig ethx down),
interrupts are disabled. With no interrupts, there is no LSC interrupt,
which is normally required to set "get_link_status", which instructs the
driver to query the device for link state. The fix is to force
get_link_status to true if the interface is not up.

Subject: e1000e: Incorrect MII Link beat reporting.

The driver was only updating MII stats when an LSC up was detected and
the interface had not already been reported up to netdev. This meant
MII stats returned in response to an SIOCGMIIREG ioctl would always
show a link up if it had ever been up. This was misleading the networking
daemon guessnet, which uses this ioctl, into making improper network port
selections.
This fix adds a call to e1000_phy_read_status() to actively read the
mii stats before responding to the SIOCGMIIREG ioctl.

From 94d8186a693284344ee5cb9734086c7a2370241a Mon Sep 17 00:00:00 2001

Subject: e1000e: cleanup ops function pointers

The phy and nvm operations structures have function pointers that contain
"phy" and "nvm" in the pointer names which are redundant since the
structures are already obviously in phy and nvm structures.

Subject: e1000e: set bools to true/false instead of 1/0

Set booleans to 'true' or 'false' to make it clear it is a boolean.  Also
change instances of TRUE/FALSE in comments to lowercase true/false.

Subject: e1000e: cleanup functions that clear hardware statistics

The e1000_clear_hw_cntrs_*() functions read the registers to clear them.
There is no reason to save the register contents so the temp variable can
be removed.

Subject: e1000e: set pm_qos DMA latency requirement per interface when needed

It was pointed out a pm_qos DMA latency requirement set when the driver is
loaded when parts that support early receive of jumbo frames are probed
could have that requirement overidden if another part supported by the
driver (one that does not support early receive of jumbo frames) is probed
later.  Change the DMA latency requirement to be per-interface if needed
instead of per driver.

Subject: e1000e: update Tx Unit hang detection message

The Tx unit hang detection code in e1000e detects other hangs caused by
hardware components (e.g. Rx, DMA units), but it is not possible to detect
exactly which component is hung so it has always assumed a Tx unit hang.
When dumping a message to the system log because of a hang, this patch adds
more data to help narrow the cause of the issue and makes the message
non-Tx-specific.  Because this new code reads PHY registers which can
sleep, move it off to a workqueue.  This and all previously existing work
tasks in the driver are now cancelled when the driver is removed.

Subject: be2net: support configuration of 64 multicast addresses instead of 32

To send upto 64 addresses in the multicast-set cmd, the non-embeeded cmd format
that provides for a bigger buffer is used instead of an embedded format.

Subject: be2net: Issue fw_init/clean cmds to fw

These cmds are issued to the fw in probe/resume and remove/suspend
paths to help fw execute some initialization and cleanup code.

This change needed the be_hw_up() code to be refactored as be_get_config().

Subject: be2net: remove BUG_ON() when be2net runs out of mccq wrbs

The driver can run out of mccq wrbs when completions don't arrive
due to an unresponsive card. This must not hit a BUG_ON(); instead
log a msg and return an error.

Subject: ixgbe: Only set/clear VFE in ixgbe_set_rx_mode

There appears to be a stray setting of the VFE bit when registering vlans.
This should not be done as vlan filtering should be enabled any time the
interface is not in promiscous mode

Subject: libipw: initiate cfg80211 API conversion (v2)

Initiate the conversion of libipw to the new cfg80211 configuration API.

For now, leave CONFIG_IPW2200_PROMISCUOUS stuff alone.  Eventually
migrate it to cfg80211 when the add/del/change_virtual_intf methods
are implemented.

(v2: Fix unconditional wiphy_unregister in libipw which was causing
     problems for ipw2100, somewhat based on prior attempted fix
     by Zhu Yi <yi.zhu@intel.com>.  Previously both original version of
     this patch and Zhu Yi's fix attempt were reverted due to
     discovery of regressions. -- JWL)

Subject: ipw2100: Register the wiphy device

libipw unconditionally calls wiphy_unregister, but it's up to the driver
to register it in the first place. ipw2100 fails to do so. Add the necessary
glue code, and also ensure that rfkill statuses get set up appropriately.

(Augmented for proper wiphy_unregister placement. -- JWL)

Subject: ipw2200: Set core hw rfkill status when hardware changes state

ipw2200 is able to detect when it's been hard-killed, but doesn't update
the core rfkill state or update userspace. Ensure that the state is updated,
allowing the rfkill core to notify userspace.

Subject: ssb: Unconditionally log results of core scans

At present, the results of an SSB core scan are only logged when
CONFIG_SSB_DEBUG is "y". As this may not be set in a distro kernel,
it is difficult interpret many problems posted in bug reports or in
help forums.

Subject: ath9k: This patch fix RX unpadding for any received frame.

It has been tested with a 802.11 frame generator and by checking the FCS field
of each received frame with the value reported by the Atheros hardware. This
patch is useful if you are trying to analyze non standard 802.11 frame going
over the air.

Subject: b43: Rewrite DMA Tx status handling sanity checks

This rewrites the error handling policies in the TX status handler.
It tries to be error-tolerant as in "try hard to not crash the machine".
It won't recover from errors (that are bugs in the firmware or driver),
because that's impossible. However, it will return a more or less useful
error message and bail out. It also tries hard to use rate-limited messages
to not flood the syslog in case of a failure.

Subject: ath5k: Fix I/Q calibration

The sign of correction coefficients was lost in the calculations, which
caused high packetloss in 802.11a mode after the results were applied.
Fixed by removing unneccesary and broken AND with a bit mask.

From: Ben Cahill <ben.m.cahill@intel.com>
Date: Fri, 20 Nov 2009 12:04:53 -0800
Subject: iwlagn: Use iwl_write8() for CSR_INT_COALESCING register

CSR_INT_COALESCING previously had only one, but now has two single-byte fields.
With only one single-byte field (lowest order byte) it was okay to write via
iwl_write32(), but now with two, an iwl_write32() to the lower order field
clobbers the other field (odd-address CSR_INT_PERIODIC_REG, offset 0x5), and an
iwl_write32() to CSR_INT_PERIODIC_REG could clobber the lowest byte of the
next-higher register (CSR_INT, offset 0x8).

Fortunately, no bad side effects have been produced by the iwl_write32()
usage, due to order of execution (low order byte was always written before
higher order byte), and the fact that writing "0" to the low byte of the
next higher register has no effect (only action is when writing "1"s).

Nonetheless, this cleans up the accesses so no bad side effects might occur
in the future, if execution order changes, or more bit fields get added to
CSR_INT_COALESCING.

Add some comments regarding periodic interrupt usage.

Subject: iwlwifi: set sm_ps_mode as part of cfg parameters

Setting "Spatial multiplexing Power Save" as part of
per device configuration parameter.

Report to uCode based on priv->conf setting, so driver can
have more control of how different devices should operate
in power save mode.

Subject: iwlwifi: reset led_tpt when clear tx/rx traffic byte counts

LED blink rate is based on the traffic load, when tx/rx traffic counts
got reset, we also need to reset the led_tpt to prevent incorrect
blink rate being calculated.

Merge both clear_tx_statistics() and clear_rx_statistics() into
single clear_traffic_statistics() function, when reset the traffic byte
counts, both tx and rx need to be reset at the same time, to make
sure calculated the correct led blink rate.

Subject: iwlwifi: separate IO tracing

Since IO tracing is usually not needed and
generates a lot of data, separate it into
its own trace system so that we can always
enable iwlwifi:* and not have to worry about
getting too much data. If IO tracing is then
really needed we can enable iwlwifi_io:* in
addition and get that data.

Subject: iwlwifi: by default, dump entire sram data portion

For "sram" debugfs file, if user did not specify the offset and length,
dump the entire data portion of sram by default.
Data portion is 0x800000 - 0x80ffff, but the actual data size is known
to the driver from the ucode file.

Subject: iwlwifi: dump error log when uCode error occurred

uCode error log contain information as to what the error was and where
it occurred necessary to debug any uCode issues.

Always log the information without special debug flag, this can help to
capture the important information when error happened.

Subject: iwlwifi: Tell the ucode immediately when association state changes

When we get a state change of associated or not, we need to tell the
ucode via the RX_ON command using the filter flags.  This will prevent
the ucode from sending any packets when not associated, specifically not
sending NULL QOS packets after a deauthentication which causes the AP to
repeatedly send deauth's in some situations.

Subject: iwlwifi: print limited number of event log when uCode error

To help iwlagn uCode debugging, event log will dump to syslog when driver
detect uCode error occurred, but this only happen when compile with
CONFIG_IWLWIFI_DEBUG and debug flag is enabled; which is not always
the case. Also, there is another problem, if the flag is set, the entire
event log buffer will be dump to syslog, it can flood the syslog and
make it very difficult to debug the problem.

Change the default to only dump last 20 entries of event log to syslog
unless the following condition meets:
1. both compile with CONFIG_IWLWIFI_DEBUG and debug flag
is enabled, and then dump the entire event buffer to syslog.
2. dump event log request from debugfs

Subject: iwlwifi: remove reset led_tpt from iwl_leds_init()

Current blinking rate is calculated based on the difference between
current tx/rx byte counts and priv->led_tpt.

priv->led_tpt should not get reset in iwl_leds_init(), this function can be
called by bring interface "up" or "down", or when uCode sysassert occurred.
resetting the led_tpt parameter will introduce incorrect led blinking behavior.

Subject: rndis_wlan: fix buffer overflow in rndis_query_oid

rndis_query_oid overwrites *len which stores buffer size to return full size
of received command and then uses *len with memcpy to fill buffer with
command.

Ofcourse memcpy should be done before replacing buffer size.

Subject: rndis_wlan: disable stall workaround

Stall workaround doesn't work with bcm4320a devices like with bcm4320b.
This workaround actually causes more stalls/device freeze on bcm4320a.
Therefore disable stall workaround by default.

Subject: ssb: Fix SPROM writing

The SPROM writing routines were broken since we rewrote the suspend
handling on wireless devices, because SPROM writing depended on suspend.

This patch changes it and freezes devices with the driver remove(), probe()
callbacks instead. This also simplifies the whole logics a lot.

Subject: ssb: Fix range check in sprom write

The range check in the sprom image parser hex2sprom() is broken.
One sprom word is 4 hex characters.
This fixes the check and also adds much better sanity checks to the code.
We better make sure the image is OK by doing some sanity checks to avoid
bricking the device by accident.

Subject: sfc: Use a single blink implementation

Only some PHYs have firmware support for a LED blink mode, so we
currently blink the others in a timer function.  Since all PHYs have
simple on and off modes, we don't gain anything by using multiple
blink implementations.  Also, since we have a process context there
is no need to use a timer.

Subject: sfc: Rename efx_board::init_leds to init_phy and use for SFN4111T

efx_board::init_leds was introduced as a second stage of
initialisation because of the inter-dependency between the board and
PHY.  We want to move board initialisation into NIC probing, which is
too early to use MDIO, so SFN4111T initialisation also needs to be
split.

Subject: sfc: Make board information explicitly Falcon-specific

Rename struct efx_board to struct falcon_board.

Introduce and use inline function to look up board info from struct
efx_nic, in preparation for moving it.

Move board init and fini calls into NIC probe and remove functions.

From f5e7adc3d4aa8edab63bb63f0ce5fe92c3dd7604 Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Mon, 23 Nov 2009 16:07:30 +0000
Subject: sfc: Combine high-level header files

All files that include ethtool.h, rx.h or tx.h are also including
efx.h, and there is no good reason to separate out the few
declarations they contain.  Therefore fold them into efx.h.

Subject: via-velocity: Correct 64-byte alignment for rx buffers

(From the VIA driver). The current code does not guarantee 64-byte
alignment since it simply does

        int add = skb->data & 63;

        skb->data += add;

(via skb_reserve). So for example, if the skb->data address would be
0x10, this would result in 32-byte alignment (0x10 + 0x10).

Correct by adding

        64 - (skb->data & 63)

instead.

Subject: via-velocity: Implement NAPI support

This patch adds NAPI support for VIA velocity. The new velocity_poll
function also pairs tx/rx handling twice which improves perforamance on
some workloads (e.g., netperf UDP_STREAM) significantly (that part is
from the VIA driver).

Subject: via-velocity: Re-enable transmit scatter-gather support

The velocity hardware can handle up to 7 memory segments. This can be
turned on and off via ethtool. The support was removed in commit

  83c98a8cd04dd0f848574370594886ba3bf56750

but is re-enabled and cleaned up here. It's off by default.

Subject: veth: move loopback logic to common location

The veth driver contains code to forward an skb
from the start_xmit function of one network
device into the receive path of another device.

Moving that code into a common location lets us
reuse the code for direct forwarding of data
between macvlan ports, and possibly in other
drivers.

We have very similar code for rx statistics in
two places in the macvlan driver, with a third
one being added in the next patch.

Consolidate them into one function to improve
overall readability of the driver.

Subject: macvlan: implement bridge, VEPA and private mode

This allows each macvlan slave device to be in one
of three modes, depending on the use case:

MACVLAN_PRIVATE:
  The device never communicates with any other device
  on the same upper_dev. This even includes frames
  coming back from a reflective relay, where supported
  by the adjacent bridge.

MACVLAN_VEPA:
  The new Virtual Ethernet Port Aggregator (VEPA) mode,
  we assume that the adjacent bridge returns all frames
  where both source and destination are local to the
  macvlan port, i.e. the bridge is set up as a reflective
  relay.
  Broadcast frames coming in from the upper_dev get
  flooded to all macvlan interfaces in VEPA mode.
  We never deliver any frames locally.

MACVLAN_BRIDGE:
  We provide the behavior of a simple bridge between
  different macvlan interfaces on the same port. Frames
  from one interface to another one get delivered directly
  and are not sent out externally. Broadcast frames get
  flooded to all other bridge ports and to the external
  interface, but when they come back from a reflective
  relay, we don't deliver them again.
  Since we know all the MAC addresses, the macvlan bridge
  mode does not require learning or STP like the bridge
  module does.

Based on an earlier patch "macvlan: Reflect macvlan packets
meant for other macvlan devices" by Eric Biederman.

Subject: macvlan: export macvlan mode through netlink

In order to support all three modes of macvlan at
runtime, extend the existing netlink protocol
to allow choosing the mode per macvlan slave
interface.

This depends on a matching patch to iproute2
in order to become accessible in user land.

Subject: sfc: Treat all MAC registers as 128-bit

Although all the defined fields in these registers are within 32 bits,
they are architecturally defined as 128-bit like most other Falcon
registers.  In particular, we must use efx_reado() to ensure proper
locking when reading MD_STAT_REG.

From 127e6e10ad17585c48cba8e1dcf30d98b90ee583 Mon Sep 17 00:00:00 2001

Subject: sfc: Fix bugs in RX queue flushing

Avoid overrunning the hardware limit of 4 concurrent RX queue flushes.
Expand the queue flush state to support this.  Make similar changes to
TX flushing to keep the code symmetric.

Subject: sfc: Hold MAC lock for longer in efx_init_port()

Although efx_init_port() is only called at probe time and so cannot
race with port reconfiguration, most of the functions it calls can
expect to be called with the MAC lock held.

Subject: sfc: Split MAC stats DMA initiation and completion
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

From: Steve Hodgson <shodgson@solarflare.com>

Currently we initiate MAC stats DMA and busy-wait for completion when
stats are requested.  We can improve on this with a periodic timer to
initiate and poll for stats, and opportunistically poll when stats are
requested.

Since efx_nic::stats_disable_count and efx_stats_{disable,enable}()
are Falcon-specific, rename them and move them accordingly.

Subject: sfc: Simplify XMAC link polling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

From: Steve Hodgson <shodgson@solarflare.com>

Only the XMAC on Falcon needs help from the driver to poll and reset
the MAC-PHY link (XAUI); GMII is a simple parallel bus and on later
NICs firmware takes care of the XAUI link.  Also, an XMAC interrupt
currently schedules a work item which simply clears a flag
(efx_nic::mac_up) to be checked by the regular monitor (or the next
link reconfiguration, if that is sooner).

Rename the flag to xmac_poll_required, changing its sense.  Remove the
needless indirection and just set the flag immediately.  Call
falcon_xmac_poll() directly where required.

Add a new generic operation mac_op::check_fault to check the link
outside of regular monitoring, as required during self-tests.

(Note that this leaves us with an unused work item, but we will
immediately have another use for it.)

Subject: sfc: Change MAC promiscuity and multicast hash at the same time
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

From: Steve Hodgson <shodgson@solarflare.com>

Currently we can set multicast hash immediately (in atomic context)
but must delay setting MAC promiscuity.  There is not that much
point in deferring one but not the other, and setting the multicast
hash on Siena will involve a firmware request.  So process them
both in efx_mac_work().

Also, set the broadcast bit in the multicast hash in
efx_set_multicast_list(), since this is required for both Falcon and
Siena.

Subject: ath9k: properly use the mac80211 rate control api

This patch changes ath9k to pass proper MCS indexes and flags
between the RC and the rest of the driver code.
sc->cur_rate_table remains, as it's used by the RC code internally,
but the rest of the driver code no longer uses it, so a potential
new RC for ath9k would not have to update it.

Subject: wl1271: fix the inetdev notifier callback return values

The wl1271_dev_notify() was returning 0 or -ENODEV, when it should return
NOTIFY_* instead.  Now we use NOTIFY_DONE when we didn't handle the event or
NOTIFY_OK when we have handled it.

For inetdev notifications, it doesn't matter whether we use NOTIFY_DONE or
NOTIFY_OK, because it ignores the return value of the call to
blocking_notifier_call_chain().  But the notify.h header says that
NOTIFY_DONE is "Don't care" and NOTIFY_OK is "Suits me", so that seems to be
the right way to do it.

Subject: wl1271: set radio and general params also for PLT

We need to set the radio and general parameters when starting PLT mode.  This
patch adds calls to TEST_CMD_INI_RADIO_PARAMS and
TEST_CMD_INIT_GENERAL_PARAMS when initializing PLT mode.

Subject: wl1271: fix radio and general parameters commands

We were missing the command header in the radio and general parameters
commands.  This was causing them to fail, resulting in problems in the power
levels and other PLT-related commands.

Also reorganized the command functions, moving from wl1271_init.c to
wl1271_cmd.c where it fits better.

Subject: wl1271: remove workaround to ignore -EIO from radio and general
 params

We were ignoring the -EIO return value from wl1271_cmd_radio_params() and
wl1271_cmd_general_params(), because they were always returning an error and
we didn't know why.  Now this has been fixed, so the workaround can be
removed.

Subject: wl1271: Remove REF_CLK hack

This hack was totally wrong and was "needed" because of a problem in the way
we were sending the GENERAL_PARMS command to the firmware.  Now that that
problem has been fixed, this hack can be removed.

Subject: rt2x00: Clean up use of rt2x00_intf_is_pci.

RT chipsets are unique across both PCI and USB busses, and don't overlap.
Therefore there is no need to test for bus type when only checking for
chipset type. Remove the redundant checks.

From e6218cc47bd54710dc523e8c983ceddba625e3ae Mon Sep 17 00:00:00 2001
From: Gertjan van Wingerde <gwingerde@gmail.com>
Date: Mon, 23 Nov 2009 22:44:52 +0100
Subject: rt2x00: Centralize setting of extra TX headroom requested by rt2x00.

Set the value of extra_tx_headroom in a central place, rather than in each
of the drivers. This is preparatory for taking alignment space into account
in the TX headroom requested by rt2x00.

When we're down, we shouldnt try to set the UMAC power limit. We just return 0
instead, and cfg80211 toggles the soft rfkill state.

Subject: iwmc3200wifi: 802.11n Tx aggregation support

To support 802.11n Tx aggregation support with iwmc3200 wifi, we have to
handle the UMAC_CMD_OPCODE_STOP_RESUME_STA_TX notification from the UMAC.
Before sending an AddBA, the UMAC synchronizes with the host in order to
know what is the last Tx frame it's supposed to receive before it will be
able to start the actual aggregation session.
We thus have to keep track of the last sequence number that is scheduled
for transmission on a particular RAxTID, send an answer to the UMAC with
this sequence number. The UMAC then does the BA negociation and once it's
done with it sends a new UMAC_CMD_OPCODE_STOP_RESUME_STA_TX notification
to let us know that we can resume the Tx flow on the specified RAxTID.

Subject: ath9k: fix processing of TX PS null data frames

When mac80211 was telling us to go into Powersave we listened
and immediately turned RX off. This meant hardware would not
see the ACKs from the AP we're associated with and hardware
we'd end up retransmiting the null data frame in a loop
helplessly.

Fix this by keeping track of the transmitted nullfunc frames
and only when we are sure the AP has sent back an ACK do we
go ahead and shut RX off.

Subject: ath9k: Proper padding/unpadding for the TX/RX path.

Software padding is done on the TX path and software unpadding is done on the
RX path. This patch corrects the position where the padding occurs. A specific
function computes the pad position and this function is used in the TX and RX
path. This patch has been tested by generating every possible 802.11 frames
with every possible frame_control field and a varying length. This patch is
useful for analyzing non standard 802.11 frames going over the air

buffer size of that of dual stream devices. Dual stream devices
have a max PCU TX FIFO size of 8 KB while single stream devices
have 4 KB. Single stream devices have an issue though and require
hardware only to use half of the amount of its capable PCU TX FIFO
size, 2 KB and this requires a change in software.

Technically a change would not have been required (except for frame
burst considerations of 128 bytes) if these devices would have been
able to use the full 4 KB of the PCU TX FIFO size but our systems
engineers recommend 2 KB to be used only. We enforce this through
software by reducing the max frame triggger level to 2 KB.

Fixing the max frame trigger level should then have a few benefits:

  * The PER will now be adjusted as designed for underruns when the
    max trigger level is reached. This should help alleviate the
    bus as the rate control algorithm chooses a slower rate which
    should ensure frames are transmitted properly under high system
    bus load.

  * The poll we use on our TX queues should now trigger and work
    as designed for single stream devices. The hardware passes
    data from each TX queue on the PCU TX FIFO queue respecting each
    queue's priority. The new trigger level ensures this seeding of
    the PCU TX FIFO queue occurs as designed which could mean avoiding
    false resets and actually reseting hw correctly when a TX queue
    is indeed stuck.

  * Some undocumented / unsupported behaviour could have been triggered
    when the max trigger level level was being set to 4 KB on single
    stream devices. Its not clear what this issue was to me yet.

Subject: ath9k: Ensure a fair beacon distribution in IBSS mode.

Update the beacon queue parameters with best effort queue parameters for
IBSS mode. This reduces the number of beacons generated by ath9k and
ensures a fair beacon distribution when there are multiple IBSS stations.
Also CWmin is quadrupled to achieve the expected percentage of
distribution.

Subject: ath9k: separate debugfs support from CONFIG_ATH_DEBUG

In my setups, ath9k's debugfs files are most of the time much more
useful than the messages generated by enabling CONFIG_ATH_DEBUG along
with the right debug flags.
Since CONFIG_ATH_DEBUG comes with a noticeable overhead on embedded
systems, this patch makes it possible to use the debugfs files without
that option.

Subject: iwmc3200wifi: Implement cfg80211 PMKSA API

We need to implement the PMKSA API for proper WPA2 pre-auth and fast
re-association. Our fullmac device generates all (re-)assoc IEs, and thus it
needs the right PMKIDs. With this implementation we now get them from
wpa_supplicant.

Subject: sfc: Simplify PHY polling

Falcon can generate events for LASI interrupts from the PHY, but in
practice we have never implemented this in reference designs.  Instead
we have polled, inserted the appropriate events, and then handled the
events later.  This is a waste of time and code.

Instead, make PHY poll functions update the link state synchronously
and report whether it changed.  We can still make use of the LASI
registers as a shortcut on the SFT9001.

Subject: sfc: QT202x: Reset before reading PHY id

Reading standard registers on the QT2025C before its firmware has
booted may cause the boot process to fail.  Therefore, follow the
recommended reset sequence before reading its id registers.  Either
order works for the QT2022C2, so don't differentiate.

Subject: sfc: Always start Falcon using the XMAC

The strap bits are only important on Falcon A and all production
boards using it have fixed-speed 10G PHYs.

Replace dummy MAC operations with default MAC operations.

The "bug9141 workaround" of setting TX_FLUSH_MIN_LEN_EN should really

Subject: ixgbe: handle parameters for tx and rx EITR, no div0

The driver was doing a divide by zero when adjusting tx-usecs.
This patch removes the divide by zero code and changes the logic slightly
to ignore tx-usecs in the case of shared TxRx vectors.

Flow Control autoneg should be disabled for certain adapters

These interfaces are the 10GBASE-T devices, CX4, and SFP+, all
running at 10 gigabit only.  1 gigabit is fine.

Subject: sfc: Turn pause frame generation on and off at the MAC, not the RX
 FIFO

Pause frame generation is gated by both RX_XOFF_MAC_EN and an enable
bit in each MAC.  RX_XOFF_MAC_EN bit always reads back as 0 so we need
to set it correctly every time we modify RX_CFG_REG.  Simplify this by
always setting it to 1 and only changing the enable bits in the MACs.

From d3245b28ef2a45ec4e115062a38100bd06229289 Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Sun, 29 Nov 2009 03:42:41 +0000
Subject: sfc: Refactor link configuration

Refactor PHY, MAC and NIC configuration operations so that the
existing link configuration can be re-pushed with:

	efx->phy_op->reconfigure(efx);
	efx->mac_op->reconfigure(efx);

and a new configuration with:

	efx->nic_op->reconfigure_port(efx);

(plus locking and error-checking).

We have not held the link settings in software (aside from flow
control), and have relied on asking the hardware what they are.  This
is a problem because in some cases the hardware may no longer be in a
state to tell us.  In particular, if an entire multi-port board is
reset through one port, the driver bindings to other ports have no
chance to save settings before recovering.

We only actually need to keep track of the autonegotiation settings,
so add an ethtool advertising mask to struct efx_nic, initialise it
in PHY init and update it as necessary.

Remove now-unneeded uses of efx_phy_op::{get,set}_settings() and
struct ethtool_cmd.

Much of this was done by Steve Hodgson <shodgson@solarflare.com>.

falcon_probe_nic_variant() does a lot less than it used to, and a
lot less than it claims to.  Fold the remainder into its caller.

From c1c4f453b61463df4df16f7aa5782fc0cfe05b9e Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Sun, 29 Nov 2009 15:08:55 +0000
Subject: sfc: Remove static PHY data and enumerations

New NICs have firmware managing the PHY, and we will discover the PHY
capabilities at run-time.  Replace the static data with probe() and
test_name() operations.

From 76884835684411264cda2f15585261eb02183541 Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Sun, 29 Nov 2009 15:10:44 +0000
Subject: sfc: Extend MTD driver for use with new NICs

In new NICs flash is managed by firmware and we will use high-level
operations on partitions rather than direct SPI commands.  Add support
for multiple MTD partitions per flash device and remove the direct
link between MTD and SPI devices.  Maintain a list of MTD partitions
in struct efx_nic.

From afd4aea03f597f29421dc5767e7d1f754730ec23 Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Sun, 29 Nov 2009 15:15:25 +0000
Subject: sfc: Add support for SFC9000 family (1)

This adds support for the SFC9000 family of 10G Ethernet controllers
and LAN-on-motherboard chips, starting with the SFL9021 'Siena' and
SFC9020 'Bethpage'.

The SFC9000 family is based on the SFC4000 'Falcon' architecture, but
with some significant changes:

- Two ports are associated with two independent PCI functions
  (except SFC9010)
- Integrated 10GBASE-T PHY(s) (SFL9021/9022)
- MAC, PHY and board peripherals are managed by firmware
  - Driver does not require board-specific code
  - Firmware supports wake-on-LAN and lights-out management through NC-SI
- IPv6 checksum offload and RSS
- Filtering by MAC address and VLAN (not included in this code)
- PCI SR-IOV (not included in this code)

Credit for this code is largely due to my colleagues at Solarflare:

   Guido Barzini
   Steve Hodgson
   Kieran Mansley
   Matthew Slattery
   Neil Turton

Subject: sfc: Add support for SFC9000 family (2)

This integrates support for the SFC9000 family of 10G Ethernet
controllers and LAN-on-motherboard chips, starting with the SFL9021
'Siena' and SFC9020 'Bethpage'.

Credit for this code is largely due to my colleagues at Solarflare:

Subject: e1000e: provide family-specific functions to manage VLAN filter
 arrays

The two MAC-families that have VLAN filter table register arrays manage
each a bit differently from one another, so provide family-specific
functions for managing the register arrays and function pointers to access
the appropriate function.  Also make sure attempts to access these
register arrays are not done on parts not supporting that feature.

Subject: e1000e: provide family-specific PHY power up/down operations

The different families (80003es2lan, 8257x, ICHx/PCH) supported by the
driver each have their own conditions when the PHY can be powered down.
This patch rewrites the PHY power up/down code to fit with the family-
specific style used in the driver.  All pre-existing calls to power up or
down the PHY remain untouched.  A new call to power down the PHY when
removing the driver when the interface is down replaces the current call
to reset the PHY in order to reduce power consumption.

From 1a40d5c170f472d541844cb5b4292efbe02ef89c Mon Sep 17 00:00:00 2001
From: Bruce Allan <bruce.w.allan@intel.com>
Date: Tue, 1 Dec 2009 15:49:51 +0000
Subject: e1000e: ensure the link state is correct for serdes links

This patch ensures that the link state (as reported in
mac->serdes_has_link) will transition to false when autoneg fails to
complete but valid codewords were detected.

Signed-off-by: Bruce Allan <bruce.w.allan@intel.com>
Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

Subject: e1000e: enable new 82567V-3 device

This new PCI device ID is for a new combination of MAC and PHY both of
which already have supporting code in the driver, just not yet in this
combination.  During validation of the device, an intermittent issue was
discovered with waking it from a suspended state which can be resolved with
the pre-existing workaround to disable gigabit speed prior to suspending.

Subject: be2net: fix unnecessary access to hardware to get link, port info

Every time while doing ethtool->get_settings we are accessing
the hardware to get link status and port information.
This is not necessary.  We now use the cached copy for this info
and update it when the link status changes.

bnx2 is failing when a PCI error is detected. The error is the
following:

bnx2: Chip not in correct endian mode
bnx2: fw sync timeout, reset code = 404001d

This error was caused because the way pci_restore_state() is working
after commit 4b77b0a2ba27d64f58f16d8d4d48d8319dda36ff ("PCI: Clear
saved_state after the state has been restored").

Subject: e1000e: remove use of skb_dma_map from e1000e driver

In testing we have found that skb_dma_map/unmap is incompatible with HW
IOMMU due to the fact that multiple mappings will return different results.
In order to correct this we need to remove skb_dma_map/unmap calls from the
e1000e driver.

Subject: ixgb: remove use of skb_dma_map from ixgb

skb_dma_map is incompatible with HW iommu due to the fact that multiple
mappings can result in different results each time.  For this reason it is
best to just remove use of these function calls.

Subject: ixgbe: remove skb_dma_map/unmap calls from driver

This patch removes skb_dma_map/unmap calls from the ixgbe driver due to the
fact that the calls don't work with HW IOMMU enabled systems.  The problem
is that multiple mappings will give different results when HW IOMMU is
enabled and the skb_dma_map/unmap calls only have one location to store
mappings.

Subject: igb: remove use of skb_dma_map from driver

This change removes skb_dma_map/unmap calls from the igb driver due to the
fact that the call is incompatible with iommu enabled kernels.  In order to
prevent warnings about using the wrong unmap call I have added a
mapped_as_page value to the buffer_info structure to track if the mapped
region is a page or a buffer.

Subject: bnx2: remove skb_dma_map/unmap calls from driver

Due to the fact that skb_dma_map/unmap do not work correctly when a HW
IOMMU is enabled it has been recommended to go about removing the calls
from the network device drivers.

[ Fix bnx2_free_tx_skbs() ring indexing and use NETDEV_TX_OK return
  code in bnx2_start_xmit() after cleaning up DMA mapping errors. -Mchan ]

Subject: e1000e: check_polarity function pointers not set for 8257x

The function pointers for 8257x devices are not set.  This is not really a
problem now because there is nothing in the driver that references the
pointers for this particular MAC-family (the appropriate functions are
called directly), but the pointers should be set in case they are used in
the future.

Subject: e1000e: refactor PHY ID detection workaround

The workaround that detects the correct PHY ID when an initial read of the
PHY ID registers returns an invalid one should retry up to ten times with
a small delay between attempts using a single PHY address and then repeat
using the remaining possible PHY addresses.  Do this instead of trying each
possible PHY address repeating that up to 100 times.

Subject: e1000e: correct ICH/PCH PHY operations function pointers

Some function pointers for a few PHY operations (for 82578 and 82567) and
were set incorrectly causing functions to be executed that were accessing
incorrect PHY register offsets for that particular device.  This patch also
moves a few PHY-specific functions from ich8lan.c to the more appropriate
phy.c.

Subject: netxen : fix debug tools access for NX2031

Driver maps only some part of the MMIO bar 0 in case of
NX2031. This is sufficient for tx and rx by the driver.
When debug tools need to access resources in
unmapped regions, driver needs to map these on the fly
in order to complete read/write request.

Subject: netxen: fix failure cases for fw hang recovery

Handle few corner cases in firmware hang detection and recovery:

o Don't mark device state as READY, till handshake with
  firmware is done.
o During probe, if start_firmware fails, restore reference
  count.
o Don't increment refernce count, if start_firmware fails
  during firmware reset.
o Clear __NX_RESETTING bit, incase of fatal error or tempeature
  reaches critical limit so that pci remove() doesn't poll on
  this bit.

Subject: sunhme: fix dma warning in Sun HME

Fix dma-api-checking warnings in Sun HME

Sun HME driver is mapping the first fragment with dma_map_single and subsequent
fragments with dma_map_page. It is unmapping all fragments with dma_unmap_single
and that produces the warning.

This patch changes it so that it unmaps only the first fragment with
dma_unmap_single and subsequent fragments are unmapped with dma_unmap_page.

It is difficult to co-relate this to the actual command that has failed.

Only files where David Miller is the primary git-signer.
wireless, wimax, ixgbe, etc are not modified.

Compile tested x86 allyesconfig only
Not all files compiled (not x86 compatible)

Added a few > 80 column lines, which I ignored.
Existing checkpatch complaints ignored.

Subject: tg3: Make TSS enable independent of MSI-X enable

The 57765 asic rev has MSI-X capability, but does not support TSS.  This
patch changes the tx paths so that TSS is explicitly mentioned, rather
than implied through the ENABLE_MSIX flag.

the accesses could collide with the pci_read_vpd() function.  This patch
converts the driver to use pci_read_vpd() to avoid any potential
collisions.

Subject: ixgbe: select FCoE Tx queue in ndo_select_queue

This removes the Tx queue selection for FCoE traffic from ixgbe_xmit_frame()
and does it in the ndo_select_queue() call, moving all Tx queue selection
into a single routine.

Subject: ixgbe: change default ring size

decrease the memory utilization of the tx / rx queue allocation
by changing the default ring size to 512 (from 1024).  At
1024 rx entries of 2KB each (from 4kB slab) with 16 queues
ixgbe was using 64 MB of memory per port, which is not
necessary.

Users can still change queue lengths with ethtool -k.

Subject: ixgbe: performance tweaks

drop variables that had cache lines modified in simultaneous hot paths.
keep some variables modified on hot paths but make their storage per queue.
cache align DMA data buffer start addresses.
cache align (padding) some structures that end within a cacheline.

Subject: ixgbe: use EIAM to automask MSI-X

when disabling interrupts, driver was writing with IO, this is no
necessary because on ixgbe parts the hardware can "oneshot"
disable and clear the interrupt.  So on 82598/82599 use of EIAM
should avoid one posted write per interrupt when in MSI-X mode.
This should improve performance and seems to in my limited
testing, reduce CPU utilization VERY slightly.

Subject: net: Fix ks8851 snl NULL pointer dereference Oops

This fixes the NULL pointer dereference Oops in the ks8851 snl network
driver during transmission.  All socket buffers from the queue are
processed inside the loop, but new workqueues have been scheduled to
run.

Subject: b43: avoid PPC fault during resume

The routine b43_is_hw_radio_enabled() has long been a problem.
For PPC architecture with PHY Revision < 3, a read of the register
B43_MMIO_HWENABLED_LO will cause a CPU fault unless b43_status()
returns a value of 2 (B43_STAT_STARTED) (BUG 14181). Fixing that
results in Bug 14538 in which the driver is unable to reassociate
after resuming from hibernation because b43_status() returns 0.

The correct fix would be to determine why the status is 0; however,
I have not yet found why that happens. The correct value is found for
my device, which has PHY revision >= 3.

Returning TRUE when the PHY revision < 3 and b43_status() returns 0 fixes
the regression for 2.6.32.

This patch fixes the problem in Red Hat Bugzilla #538523.

Subject: b43legacy: avoid PPC fault during resume

For PPC architecture with PHY Revision < 3, a read of the register
B43_MMIO_HWENABLED_LO will cause a CPU fault unless b43legacy_status()
returns a value of 2 (B43legacy_STAT_STARTED); however, one finds that
the driver is unable to associate after resuming from hibernation unless
this routine returns 1. To satisfy both conditions, the routine is rewritten
to return TRUE whenever b43legacy_status() returns a value < 2.

This patch fixes the second problem listed in the postings for Red Hat
Bugzilla #538523.

Subject: ipw2100: fix rebooting hang with driver loaded

Add PCI .shutdown method so that we can disable the device during
shutdown or reboot. Without this, the reboot doesn't work well on
some platforms.

This fixes http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2124

Subject: iwl3945: remove duplicated event logging code

In the process of improving uCode event logging capability, the new
implementation was introduced without removing the existing
implementation. The event log will be dumped to dmesg twice.
Remove the old implementation to only log the event once upon sys
assert or request by user.

Subject: iwlwifi: driver version track kernel version

The driver version number is a remnant from when there was an out-of-tree
iwlwifi driver. Now that the driver forms part of kernel source we do not
need a separate driver version. Instead, we now use the kernel version as
driver version. We maintain the previous tags used to indicate which
components the driver has been compiled with.

Subject: iwmc3200wifi: Coex table command does not expect a response

When sending the wiwi coexistence priority table, we should not tell the LMAC
that we want a response.

Subject: iwmc3200wifi: Add wifi-wimax coexistence mode as a module parameter

Wifi and wimax coexistence mode is set by wifi at boot time. There can be
several modes, defined by priority tables. User space components can decide
which one to select by writing to /sys/module/iwmc3200wifi/parameters/wiwi
with this patch, before bringing the interface up.

Subject: iwmc3200wifi: Enable wimax core through module parameter

When debugging the wifi firmware, we need to disable the wimax core to gain
some memory space. The default value will keep the wimax core enabled.
