In this patch there's no distinction, but after adding the off-channel
powersave state there is -- disabled == !enabled && !offchannel.
Actually one of the last bugs I fixed before sending these was a place
where I had used disabled instead of !enabled, and the frames ended up
with PM set when it shouldn't have been.
I agree though that the distinction is confusing. Maybe some better
state names are needed. Perhaps awake, offchannel, and doze?

That's true. Would moving it to ieee80211_i.h be appropriate, or is
there somewhere better?
