Oleksij, yes, that's correct, it includes entire Linux environment; the
reasoning is that it allows to hide all WiFi-related logic inside device
itself, and emulate simple Ethernet device for external system
(therefore, freeing external system resources).

This approach was working really well for us until recently, but now
that company is expanding, we want to have more flexible and standardize
interface available for external system to manage wireless connection,
and FullMAC driver seems to be the best solution here.
you mean, this driver will not use mac80211 framework provided by kernel?
Yes, this driver is FullMAC - converting Quantenna drivers codebase to
mac80211 framework will require significant effort from developers and
QA, but I think in the future it will have to be done anyway.
Why? The linux wireless subsystem supports both models, ie.
cfg80211-based drivers and mac80211-based drivers, so there is no
technical reason for making the effort. There are clearly benefits in
using a generic and freely available 802.11 stack like mac80211.
