Change 135035 by sephe@sephe_zealot:sam_wifi on 2008/02/08 11:50:57

	Do not update peer node sequence, if a multicast frame is received.
	This should make STA mode work better with broken APs, which do not
	support WME but use different sequence spaces for ucast and mcast
	frames.
	
	Discussed with: sam
	Obtained from: DragonFly
