Subject: rt2x00 and hostapd

rt2x00 doesn't work with hostapd, the driver seems to wrongly interpret the
carrier state and refuse to send beacons if there is no carrier.
there is a workaround out there to fix this (see below), but the right way
would be to have this done similar to other mac80211 driver which do not
require this workaround.
anyone got an idea what's wrong here?

I think this needs to be sorted out upstream. As far as I know, nobody
so far has figured out yet why managing the netdev carrier state causes
the hostapd issues and why it appears to only happen on rt2x00.
