[...] 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.
