no, unfortuately i have no idea. also i should admit that we have problems 
with atheros hardware in that we don't know when the RX timestamp is taken 
exactly. this means our IBSS merge can't be 100% exact. but the usual case we 
need to catch is when the beacon TSF is much higher than the local TSF. 

i don't care about IBSS power-save right now.

true, we need to find a way to support this hardware too...
