0866b03c7d b43/b43legacy: Wake queues in wireless_core_start
If b43 or b43legacy are deauthenticated or disconnected, there is a
possibility that a reconnection is tried with the queues stopped in
mac80211. To prevent this, start the queues before setting
STAT_INITIALIZED.

In b43, a similar change has been in place (twice) in the
wireless_core_init() routine. Remove the duplicate and add similar
code to b43legacy.

b6c3f5be7c b43: Fix throughput regression
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.

96869a3939 b43: Workaround circular locking in hw-tkip key update callback
The TKIP key update callback is called from the RX path, where the driver
mutex is already locked. This results in a circular locking bug.
Avoid this by removing the lock.

Johannes noted that there is a separate bug: The callback still breaks on SDIO
hardware, because SDIO hardware access needs to sleep, but we are not allowed
to sleep in the callback due to mac80211's RCU locking.

b3fbdcf49f mac80211: pass vif and station to update_tkip_key
When a TKIP key is updated, we should pass the station
pointer instead of just the address, since drivers can
use that to store their own data. We also need to pass
the virtual interface pointer.
