Looking at the changes, lets see if we can get some more review on this:

The wiphy->interface_modes thing is probably fall-out from commit
8dffff216fcac4f79078478085e86d68db64922e ("mac80211: only create default
STA interface if supported"). I'm cc'ing Johannes.

And the IEEE80211_HW_SIGNAL_UNSPEC and ->max_signal from commit
566bfe5a8bcde13188a356f77666f8115813cf31 ("mac80211: use hardware flags
for signal/noise units"). Lets cc Bruno.
