The PDU length of incoming LLC frames is set to the total skb payload size in __ieee80211_data_to_8023() of net/wireless/util.c which incorrectly includes the length of the IEEE 802.11 header. The resulting LLC frame header has a too large PDU length, causing the llc_fixup_skb() function of net/llc/llc_input.c to reject the incoming skb, effectively breaking STP. Solve the problem by properly substracting the IEEE 802.11 frame header size from the PDU length, allowing the LLC processor to pick up the incoming control messages. Special thanks to Gerry Rozema for tracking down the regression and proposing a suitable patch. Fixes FS#24.
