I have not succeeded to setup vlan bridging even with 4.6. Looking in source
code :
if_vlan.c :
[...]
case SIOCSIFFLAGS:
/*
* We don't support promiscuous mode
* right now because it would require help from the
* underlying drivers, which hasn't been implemented.
*/
if (ifr->ifr_flags & (IFF_PROMISC)) {
ifp->if_flags &= ~(IFF_PROMISC);
error = EINVAL;
}
break;
[...]
In if_ethersubr.c ether_demux() it's easy to see that vlan packets with
unicast mac addresses different of parent mac would be dropped.
for freebsd 4.4 I have wrote small patch to allow promisc mode on vlan
interfaces and bridgiing of vlan interfaces. If you are interested I will
renew it for 4.6.
regards,
misho
