No, I'm sure I want it the way I said. I know it sounds wrong,
but I just don't have enough PCI-X slots to waste 2 on physical
100M NICs for the uplink from the routers.

Trunking is a way of combining multiple physical interfaces to
increase the bandwidth. Trunking multiple VLANs on a single
interface doesn't make sense to me.

802.1q is VLAN tagging and trunking. This interface is LACP - link
aggregation. I really think that it makes no sense to be able to
aggregate some ethernet interfaces and not others. I suppose some
pedant will tell me vlan interfaces are not ethernet.

I think the unfortunate name of trunk(4) that we inherited from OpenBSD
is causing quite some confusion. trunk(4) actually has nothing to do
with vlan trunking which I think you are after.

I can see this topic coming up again so it could save some time to
rename the driver now. It would mean that we lose the naming link to
the same driver in OpenBSD but you cant win em all.

Some names that have been suggested are:

linkag(4)
agr(4)
bond(4) <- same as linux

Any suggestions!

team(4)
group(4)
gang[bang](4)

;-) .. I'd prefer if we keep the name and a compatible interface as it
will allow to reuse documentation.
