Even just inlines in ieee80211.h or something for chan->freq, freq->chan, freq->band, chan->band, etc. Max allowed power levels and stuff as well. WRT to userspace, if there's an easy way to put this into headers that get exported to userspace headers, I think that would be useful. Otherwise everybody has to keep rewriting these, both mac80211, fullmac drivers, userspace programs like NetworkManager and wpa_supplicant, etc. Dan > themselves and introduce bugs and be updated all the time for new > things.
