I mean is there anyone who really uses >4 VLs?  Presumably the
HW designers didn't think so, because they limited HW to 4 VLs
with 4K MTU.

At least can we make this a runtime thing?  If we're able to set a
port as IB vs ethernet then # of VLs seems like it should be doable too.

And 4K MTU should probably be the default, since almost all users
want 4K MTU vs. caring about VLs.  (Probably 99% of IB users
never set SL of anything)
