I think that keeping backward compatibility is a good idea and I'm ok
to remove the warning message even though I don't think it does any
harm.  I will modify the patch to document the fact that vlan=  is not
IEEE 902.1q and that vnet= is the prefered option.

I really think that it's a change that should done, both in the code
and usage as both will greatly benefit from a move to VNET. Just look
at the actual naming mess in e1000.c where real 802.1q handling takes
place as well...
