I don't know whether you are still interested to track down the wired

If you have time please try following patches:

revert the old patch at your AP side and try this one
http://people.freebsd.org/~sephe/rt2560_test.diff1

apply following patch at you STA side
http://people.freebsd.org/~sephe/ieee80211_input.c.diff
