Stanse found that i2400m_rx frees skb, but still uses skb->len even
though it has skb_len defined. So use skb_len properly in the code.
And also define it unsinged int rather than size_t to solve
compilation warnings.

Stanse found that ia_init_one locks a spinlock and inside of that it
calls ia_start which calls:
* request_irq
* tx_init which does kmalloc(GFP_KERNEL)
Both of them can thus sleep and result in a deadlock. I don't see a
reason to have a per-device spinlock there which is used only there
and inited right before the lock location. So remove it completely.

Stanse found we do in console_show:
kfree_skb(skb);
return skb->len;
which is not good. Fix that by remembering the len and use it in the
function instead.

with hardware slow in negotiation, the system did freeze
while trying to mount root on nfs at boot time.
the link state has not been initialised so network stack
tried to start transmission right away. this caused instant
retries, as the driver solely stated business upon link down,
rendering the system unusable.
notify carrier off initially to prevent transmission until
phylib will report link up.

setup.phone and setup.eazmsn are 32 character buffers.
rcvmsg.msg_data.byte_array is a 48 character buffer.
sc_adapter[card]->channel[rcvmsg.phy_link_no - 1].dn is 50 chars.
The rcvmsg struct comes from the memcpy_fromio() in receivemessage().
I guess that means it's data off the wire. I'm not very familiar with
this code but I don't see any reason to assume these strings are NULL
terminated.
Also it's weird that "dn" in a 50 character buffer but we only seem to
use 32 characters. In drivers/isdn/sc/scioc.h, "dn" is only a 49
character buffer. So potentially there is still an issue there.
The important thing for now is to prevent the memory corruption.

move paramater definitions to a device paramater structure only
leaving the device name, which antennas are used and what firmware
file to use in the iwl_cfg structure. this will not completely
remove the redundancies but greatly reduce them for devices that
only vary by name or antennas. the parameters that are more
likely to change within a given device family are left in iwl_cfg.
also separate bt param structure added to help reduce more.

This reverts commit 030725d2c7c1fafec7ede618647bf30ed79601f0.
This commit relies on commit 5ed3bc7288487bd4f891f420a07319e0b538b4fe
("mac80211: use netif_receive_skb in ieee80211_tx_status callpath")
Unfortunately not all drivers are calling ieee80211_tx_status from a
compatible context, so that commit needs to be reverted in 2.6.36.

This reverts commit 7acc7c683a747689aaaaad4fce1683fc3f85e552. It was
applied to avoid possible warning in ieee80211_restart_hw, however
reason of the warning were races in mac80211, currently hopefully fixed.
Not reseting device when performing scan is bad for two reasons.
When forcing reset from iwl_check_stuck_queue(), in case of fail,
reset will be repeated until scan finish. But since firmware is in bad
shape, scan only finish after scan_check work (about 7s). So we will
delay the reset, what is not good behaviour.
When forcing reset from iwl_recover_from_statistics(), we will not
repeat the reset, so we will not perform reset at all when needed.

with an arbitrary size of 255, move the ANI state into the channel struct.
Move some config settings that are not per-channel out of

Throughout the code, DISABLE_REGWRITE_BUFFER is always called right after
REGWRITE_BUFFER_FLUSH. Since that's unlikely to change any time soon, that
makes keeping those ops separate rather pointless, as it only increases
code size and line number counts.

The cycle counters are used by ANI to determine the amount of time that the
radio spent not receiving or transmitting. They're also used for debugging
purposes if the baseband watchdog on AR9003 detects a lockup.
In the future, we want to use these counters to determine the medium utilization
and export this information via survey. For that, we need to make sure that
the counter is only accessed from one place, which also ensures that
wraparounds won't occur at inconvenient points in time.

The calibration actual calibration flags are only used by the per chip family
source files, so it makes more sense to define them in those files instead
of globally. That way the code has to test for less flags.
Also instead of using a separate callback for testing whether a particular
calibration type is supported, simply adjust ah->supp_cals in the calibration
init which is called right after the hardware reset, before any of the
calibrations are run.
