during suspend/S3 state drv_flush is called from mac80211 irrespective of
interface count. In ath9k we queue a work in ath9k_flush which we expect
to be cancelled in the drv_stop call back. during suspend process mac80211
calls drv_stop only when the interface count(local->count) is non-zero.
unfortunately when the network manager is enabled, drv_flush is called
while drv_stop is not called as local->count reaches '0'.
So fix this by simply checking for the device presence in the
drv_flush call back in the driver before queueing work or anything else.
this patch fixes the following WARNING

The patch 'ath9k_hw: fix stopping rx DMA during resets' added code to detect
a condition where rx DMA was stopped, but the MAC failed to enter the idle
state. This condition requires a hardware reset, however the return value
of ath_stoprecv was 'true' in that case, which allowed it to skip the reset
when issuing a fast channel change.

Pass the correct module name and device interface so that
ethtool can display the proper values.
The firmware version will be fixed later on when the FW
can actually report a version. :)

During PHY errors, the MAC can sometimes fail to enter an idle state on older
hardware (before AR9380) after an rx stop has been requested.
This typically shows up in the kernel log with messages like these:
ath: Could not stop RX, we could be confusing the DMA engine when we start RX up
------------[ cut here ]------------
WARNING: at drivers/net/wireless/ath/ath9k/recv.c:504 ath_stoprecv+0xcc/0xf0 [ath9k]()

When this happens, the state that the MAC enters is easy to identify and
does not result in bogus DMA traffic, however to ensure a working state
after a channel change, the hardware should still be reset.
This patch adds detection for this specific MAC state, after which the above
warnings completely disappear in my tests.

Joe Culler reported a problem with his AR9170 device:
> ath: EEPROM regdomain: 0x5c
> ath: EEPROM indicates we should expect a direct regpair map
> ath: invalid regulatory domain/country code 0x5c
> ath: Invalid EEPROM contents
It turned out that the regdomain 'APL7_FCCA' was not mapped yet.
According to Luis R. Rodriguez [Atheros' engineer] APL7 maps to
FCC_CTL and FCCA maps to FCC_CTL as well, so the attached patch
should be correct.

Some clients seem to rely upon the reception of BlockAckReqs to flush
their rx reorder buffer. In order to fix aggregation for these clients
carl9170 should set IEEE80211_TX_STAT_AMPDU_NO_BACK to generate a
BlockAckReq if the transmission of an AMPDU subframe fails.
This fixes aggregation problems with Intel 5100 Windows STAs (and maybe
others as well).

commit 86271e460a66003dc1f4cbfd845adafb790b7587 introduced a
regression that caused mac80211 queues in stopped state.
ath_drain_all_txq is called in driver flush which would reset
the stopped flag and the mac80211 queues were never started
after that. iperf traffic is completely stalled due to this issue.
Restart the mac80211 queues in driver flush only if the txqs were
drained.

With the recent tx status optimization in mac80211, we bail out as
and and when invalid rate index is found. So the behavior of resetting
rate idx to -1 and count to 0 has changed for the rate indexes that
were not part of the driver's retry series.
This has resulted in ath9k using incorrect rate table index which
caused the system to panic. Ideally ath9k need to loop only for the
indexes that were part of the retry series and so simply use hw->max_rates
as the loop counter.
Pasted the stack trace of the panic issue for reference.

Kernel panic occurs just after AR2427 establishes connection with AP.
Unless aggregation is enabled we don't initialize the TID structure.
Thus accesing the elements of the TID structure when aggregation is
disabled, leads to NULL pointer dereferencing.

Some clients seems to keep track of their reorder window even after an
aggregation session has been disabled. This causes issues if there are
still retried but not completed frames pending for the TID.
To ensure that rx does not stall in such situations, set sendbar to 1
for any frame purged from the TID queue on teardown.

ath9k calls ath9k_hw_stoptxdma every time it sends a beacon, however there
is not much point in doing that if the previous beacon and mcast traffic
went out properly. On AR9380, calling that function too often can result
in an increase of stuck beacons due to differences in the handling of the
queue enable/disable functionality.
With this patch, the queue will only be explicitly stopped if the previous
data frames were not sent successfully. With the beacon code being the
only remaining user of ath9k_hw_stoptxdma, this function can be simplified
in order to remove the now pointless attempts at waiting for transmission
completion, which would never happen at this point due to the different
method of tx scheduling of the beacon queue.

This patch simplifies the flush op and reuses ath_drain_all_txq for
flushing out pending frames if necessary. It also uses a global timeout
of 200ms instead of the per-queue 60ms timeout.

In some situations, stopping Tx DMA frequently fails, leading to messages
like this:
ath: Failed to stop TX DMA in 100 msec after killing last frame
ath: Failed to stop TX DMA!
This patch uses a few MAC features to abort DMA globally instead of iterating
over all hardware queues and attempting to stop them individually.
Not only is that faster and works with a shorter timeout, it also makes the
process much more reliable.
With this change, I can no longer trigger these messages on AR9380,
and on AR9280 they become much more rare.

The hardware rx filter flag triggered by FIF_PROMISC_IN_BSS is overly broad
and covers even frames with PHY errors. When this flag is enabled, this message
shows up frequently during scanning or hardware resets:
ath: Could not stop RX, we could be confusing the DMA engine when we start RX up
Since promiscuous mode is usually not particularly useful, yet enabled by
default by bridging (either used normally in 4-addr mode, or with hacks
for various virtualization software), we should sacrifice it for better
reliability during normal operation.
This patch leaves it enabled if there are active monitor mode interfaces, since
it's very useful for debugging.

The return value of the tx operation is commonly
misused by drivers, leading to errors. All drivers
will drop frames if they fail to TX the frame, and
they must also properly manage the queues (if they
didn't, mac80211 would already warn).
Removing the ability for drivers to return a BUSY
value also allows significant cleanups of the TX
TX handling code in mac80211.
Note that this also fixes a bug in ath9k_htc, the
old "return -1" there was wrong.
