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

- 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

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.

iwlagn: update write pointers for all tx queues after wakeup
Wakeup interrupt has been updating write pointers (indexes, actually) only

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

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.

mac80211: deprecate qual value
This value is unused by mac80211, because it was only
be used by wireless extensions, and turned out to not
be useful there because the quality value needs to be
comparable between scan results and the current value
which is impossible when the qual value is calculated
taking into account noise, for example.
Since it is unused anyway, this patch deprecates it
in the hope that drivers will remove their sometimes
quite expensive calculations of the value.
I'm open to actual uses of the value, but the best
way of using it seems to be what the Intel drivers do
which should probably be generalised if we have noise
values from the hardware.
