g-command/
Adding a means to create lagged interfaces might be a good idea,
but that's also more complicated than setting up a vlan interface.
The problem from a user perspective with how we present vlans in
FreeBSD is that it isn't tied directly to an interface, so it's
confusing for newbies when they're trying to grok how vlans work.
In general you have a couple properties to make the user aware of:
1. My parent interface.
2. My vlan tag.
3. Other good stuff like MTU, HW Filters (which I've never used),
HW TSO, etc.
MTU is also kind of tricky because you can set a vlan interface's
MTU to something greater than the MTU of the lower interface and
things won't fail properly IIRC (or maybe that was just a bug in
FreeNAS.. I forget).
Cheers,
