2012-01-06	gprs: Honor GSM 04.64 8.4.2 Receipt of unacknowledged information	Holger Hans Peter Freyther	1	-0/+16
	GSM 04.64 8.4.2 asks to ignore UI frames if the DLCI is not known, or if the "(V(UR)- 32) <= N(U) < V(UR)". E.g. if we want to have V(UR) == 511 and this frame is dropped, we would ignore N(U)'s 0 to 510. Calculate the delta. The code is based on Jonathan Santos's "LLC UI window" fix but the issue was discovered independly.
