Since I've recently needed it, neither bridge.c nor if_bridge.c allow
you to bridge VLAN trunks (you can bridge individual VLANs but that
becomes unwieldly when you have dozens of VLANs). I have code to do
this in bridge.c.

Since if_bridge.c does not exist in FreeBSD 5, and there has not
previously been any suggestion that bridge.c is deprecated, I would
object to the removal of bridge.c from FreeBSD 6 since this would
violate the standard deprecation cycle.

Has anyone looked at how difficult it would be to get if_bridge.c to
work in 5.x?
