        sys/net/if_vlan.c: revision 1.125

Fix the handling of the state returned from pfil_run_hooks().

pfil_run_hooks() invokes any registered packet filters on the packet
being handled.  It may return a (non-zero) errno, indicating that a
filter has decided that the packet should be discarded, and has freed
the mbuf.  While a non-error (0) return usually means that the packet
should be processed normally, a filter may still free the mbuf if the
packet is a fragment, and the filter is holding it for reassembly and
future evaluation.  Therefore, there must be separate tests for the
return value and for a possible discarded packet.  (See pfil(9).)

OK: christos, martin
