[PATCH] rt2x00: Implement SW diversity
When mac80211 indicates that the default antenna setup
should be used _and_ that this default setup is SW_DIVERSITY.
This requires sampling and storing the RSSI per antenna
and check once every 2 seconds to determine if the RSSI
has changed significantly. Once this is the case we should sample
the other antenna for a short period and evaluate if
we need to swap antenna or not.
