We decide this with françois as an alternative to desactivate the NIC 
vlan filtering instead of creating a modul parameter.
The vlan id 0 need to be created but not necessary activate.

In september 2008, we had a discution about exactly the same problem.
You speak about the possibility of an ALLVLAN device flag.

I think i proposed a patch to desactivate NIC vlan filtering when we are 
in promisc mode but not used.
