It extends the interface between the 802.11 stack and drivers so that
drivers can avoid sending QoS frames to APs that don't support them.
There is no new interface to userland.  My understanding is that iwlwifi
becomes unable to communicate with non-QoS-capable APs after having once
associated with a QoS-capable AP, without this and the following change
in iwlwifi itself.

Once a job is fouled up, anything done to improve it makes it worse.
