The regulatory domain structures, channel information (struct
ieee80211_channel), HW mode (struct ieee80211_hw_mode) compromised of
supported channels and rates, and probably a few others in the same
category. I can't see the possibility of using d80211 as it stands
(designed for softmac cards dealing with 802.11 packets to/from the OS).

However, it does not make any sense to use the structures defined by
d80211 if not effectively using it (we send/receive 802.3 frames to the
firmware, after all), IMO.

As discussed on this thread, there is a lot of code to be cleanup up,
but no structural changes AFAICT. Is there a general agreement on that,
now?
