get_tx_stats() will be removed from mac80211.
mwl8k used struct ieee80211_tx_queue_stats internally to track the queue
lenght. Replace struct ieee80211_tx_queue_stats with a simple len field
in struct mwl8k_tx_queue. Limit and count fields seemed to be unused.

When running directed active scans we currently end up sending both the SSID
probe requests and an additional broadcast one.
This is due to the fact that we always leave the probe request template SSID IE
length to 0. Instead we should set it to the first SSID to scan, and fill the
direct_scan array with the remaining SSIDs to scan for. This way we only send
what we've been asked to: a broadcast probe request when no directed scan is
requested, and directed probe requests otherwise.

Existing iwl6050_ops->iwl6050_hcmd_utils structure had no pointers to chain
noise functions (gain_computation and chain_noise_reset). As it turns out,
by adding chain_noise_scale (see related patch), there is no need for separate
chain noise function, so simply use iwl6000_ops->iwl5000_hcmd_utils, and
remove those for 6050.

Retrying commands seldomly works, most often the firmware is in a
weird state anyway and needs the device to reset. So it's better
to report the broken state back to user-space.
Also rename command_timer_fn() into lbs_cmd_timeout_handler(),
which better reflect it's usage.

For debugging hardware scan trigger/complete
functionality, it was useful to have code in
hwsim that pretends to do a hardware scan.
This code could be extended to actually do the
scan, but for now it was sufficient for me to
only pretend. Since hwsim was written to ease
debugging, it only makes sense to add it to it
permanently.

Commit c7ab5ef9bc entitled "b43: implement
short slot and basic rate handling" reduced the transmit throughput for
my BCM4311 device from 18 Mb/s to 0.7 Mb/s. The basic rate handling
portion is OK, the problem is in the short slot handling.
Prior to this change, the short slot enable/disable routines were never
called. Experimentation showed that the critical part was changing the
value at offset 0x0010 in the shared memory. This is supposed to contain
the 802.11 Slot Time in usec, but if it is changed from its initial value
of zero, performance is destroyed. On the other hand, changing the value
in the MMIO register corresponding to the Interframe Slot Time increased
performance from 18 to 22 Mb/s. A BCM4306/3 also shows dramatic
improvement of the transmit rate from 5.3 to 19.0 Mb/s.
Other changes in the patch include removal of the magic number for the
MMIO register, and allowing the slot time to be set for any PHY operating
in the 2.4 GHz band. Previously, the routine was executed only for G PHYs.

of the ath_bus_cleanup() calls. Take care not to use any device data
