Subject: [PATCH wireless v2 0/4] wifi: b43: Various QoS-related fixes

Recently acquired a MacBookPro8,3 (early 2011), which has a bcm4331 card.
Noticed some issues with the wireless driver, specifically related to QoS, when
using this device.

Out of the box, applications like ssh appear to not work with the device when
QoS is enabled. This series attempts to improve the out-of-box experience while
cleaning up some fundamental issues in the driver when QoS is disabled, either
by the related kernel parameter or the newly introduced QoS disablement
function.

Running FW 784.2 during testing.
