This seems a different problem to me.  Can't tell if it still exists.
Perhaps it has to do with doing promiscuous mode (tcpdump) and hardware
tagging on bge0 at once.  We saw this problem on em(4) already.  Alas,
my test machine with bge(4) will stay down for quite a while.

Keep in mind that that patch hides the problem instead of fixing it.

The problem was fixed in CURRENT yesterday by glebius at .
If you would like to stay with 6.0-BETA3 for now, please
apply the following patch to /sys/net/if_vlan.c:


Than you'll be able to use the unpatched if_bge.c.
