Pull up revision 1.30 (requested by bouyer in ticket #1356):

Make promiscous mode work on vlans: introduce a new link-layer m_flag
M_PROMISC. In ether_input(), flag packets comming from an interface in
promiscous mode which are not for us M_PROMISC instead of droping them.
Drop M_PROMISC packets which are not passed to vlan_input(). M_PROMISC
packets passed to vlan_input() will be looped back to ether_input()
the M_PROMISC flag will be handled appropriately.
Clear M_PROMISC before giving the packet to bridge, as bridge has its
own checks for local MAC addresses.
This also makes bridges on vlan working.
