Fix from [EMAIL PROTECTED], STP packets are incorrectly received on all
LLC datagram sockets, whichever interface they are bound to.
The llc_sap datagram receive logic sends packets with a unicast destination
MAC to one socket bound to that SAP and MAC, and multicast packets to all
sockets
bound to that SAP. STP packets are multicast, and we do need to know
on which interface they were received.
