The rt2x00dev->intf_work workqueue is never initialized when a driver is
probed for a non-existent device (in this case rt2500usb). On such a
path we call rt2x00lib_remove_dev() to free any resources initialized
during the probe before we use INIT_WORK to initialize the workqueue.
This causes lockdep to get confused since the lock used in the workqueue
hasn't been initialized yet but is now being acquired during
cancel_work_sync() called by rt2x00lib_remove_dev().
Fix this by initializing the workqueue first before we attempt to probe
the device. This should make lockdep happy and avoid breaking any
assumptions about how the library cleans up after a probe fails.
phy0 -> rt2x00lib_probe_dev: Error - Failed to allocate device.
INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.

"hostap: Protect against initialization interrupt" (which reinstated
"wireless: hostap, fix oops due to early probing interrupt")
reintroduced Bug 16111. This is because hostap_pci wasn't setting
dev->base_addr, which is now checked in prism2_interrupt. As a result,
initialization was failing for PCI-based hostap devices. This corrects
that oversight.

When there is a firmware error or the firmware is reloaded for some other
reason we currently clear all station information, including keys
associated with them. A problem is that we do not clear some other
information regarding keys that are not stored in the station structs.
The consequence of this is that when the device is reconfigured after the
firmware reload we can, among other things, run out of key indices.
This fixes:

Without setting this bit the firmware will not examine the RTS/CTS setting

required for HT traffic in a noisy environment where, without this setting,
connections will stall on some hardware as documented in the patch that

iwlwifi: Fix throughput stall issue in HT mode for 5000
Similar to 6000 and 1000 series, RTS/CTS is the recommended
protection mechanism for 5000 series in HT mode based on the HW design.
Using RTS/CTS will better protect the inner exchange from interference,
especially in highly-congested environment, it also prevent uCode encounter
TX FIFO underrun and other HT mode related performance issues.
For 3945 and 4965, different flags are used for RTS/CTS or CTS-to-Self
protection.

Date: Thu Apr 29 04:43:05 2010 -0700
iwlwifi: apply filter flags directly
broke multicast. The reason, it turns out, is that
the code previously checked if ALLMULTI _changed_,
which the new code no longer did, and normally it
_never_ changes. Had somebody changed it manually,
the code prior to my patch there would have been
broken already.
The reason is that we always, unconditionally, ask
the device to pass up all multicast frames, but the
new code made it depend on ALLMULTI which broke it
since now we'd pass up multicast frames depending
on the default filter in the device, which isn't
necessarily what we want (since we don't program it
right now).
Fix this by simply not checking allmulti as we have
allmulti behaviour enabled already anyway.

There are few places where ANI is started without checking
if it is right to start. This might lead to a case where ani
timer would be left undeleted and cause improper memory acccess
during module unload. This bug is clearly exposed with
paprd support where the driver detects tx hang and does a
chip reset. During this reset ani is (re)started without checking
if it needs to be started. This would leave a timer scheduled
even after all the resources are freed and cause a panic.
This patch introduces a bit in sc_flags to indicate if ani
needs to be started in sw_scan_start() and ath_reset().
This would fix the following panic. This issue is easily seen
with ar9003 + paprd.

The flow id (scd_flow) in a compressed BA packet should match the txq_id
of the queue from which the aggregated packets were sent. However, in
some hardware like the 1000 series, sometimes the flow id is 0 for the
txq_id (10 to 19). This can cause the annoying message:
[ 2213.306191] iwlagn 0000:01:00.0: Received BA when not expected
[ 2213.310178] iwlagn 0000:01:00.0: Read index for DMA queue txq id (0),
index 5, is out of range [0-256] 7 7.
And even worse, if agg->wait_for_ba is true when the bad BA is arriving,
this can cause system hang due to NULL pointer dereference because the
code is operating in a wrong tx queue!

Grant patches added an of mach table to struct device_driver. However,
while he changed the macio device code to use that, he left the match
table pointer in struct macio_driver and didn't update drivers to use
the "new" one, thus breaking the probing.
This completes the change by moving all drivers to setup the "new"
one, removing all traces of the old one, and while at it (since it
changes the exact same locations), I also remove two other duplicates
from struct driver which are the name and owner fields.

We can wake all queues after a chip reset since everything should be set up and
we are ready to transmit. If we don't do that we might end up starting up with
stopped queues, not beeing able to transmit. (This started to happen after
"ath5k: clean up queue manipulation" but since periodic calibration also
stopped and started the queues this effect was hidden most of the time).
This way we can also get rid of the superfluous ath5k_reset_wake() function.

Wrong buffer is checked for bf_tx_aborted field in ath_tx_num_badfrms(),
this may result in a rate scaling with wrong feedback (number

of buffers for an aggregate frame that should be checked.
Also it misses the initialization of this field in the buffer,
