This looks very interesting. I'm busy testing with a switch that
claims 802.3ad support.

We're making extensive use of vlans to increase the number of
interfaces availabble to us using switches to break out gigE into
100M interfaces. The bandwidth problem we're having is to our
provider, a 100M connection, and we're looking at doing exactly
this. However, it appears that this interface can't trunk vlan
interfaces.

It sounds like you want it the other way around. The trunk should be the
lowest component in any setup so you should vlan the trunk interface
rather than trunk a vlan.

ifconfig trunk0 create
...
ifconfig vlan0 vlan 10 vlandev trunk0

(or use ifconfig trunk0.10 create which is a better syntax)

Andrew
