[This patch applies only to 2.6.36 stable. The problem was introduced in that release and is already fixed by larger changes to the vlan code in 2.6.37.] Normally hardware accelerated vlan packets are quickly dropped if there is no corresponding vlan device configured. The one exception is promiscuous mode, where we allow all of these packets through so they can be picked up by tcpdump. However, this behavior causes a crash if we actually try to receive these packets. This fixes that crash by ignoring packets with vids not corresponding to a configured device in the vlan hwaccel routines and then dropping them before they get to consumers in the network stack.
