There's even two ways of implementing this:
1) the easy way -- just check for received frames in mac80211
2) the good way -- ask the driver to notify us of _any_ received frames
or poll the driver or something like that
1) is clearly very easy, but if it's seeing e.g. a control frame or a
frame for a different BSS then the device might not pass it up.
But to be honest, I wouldn't worry about 2) and let Jouni implement it
if he cares :) And if we want to make this improvement, 1) is good for
all hardware anyway.
