I guess it hasn't been added yet since no one knew how outgoing VLAN support 
should look like. for example, I wouldn't have thought that it would be useful 
to support different VLAN tags on the same IP address. Instead, I would have 
added multiple netifs each with their own IP address or subnet and assigned a 
VLAN tag to the netif.

Honestly, I wouldn't want to add a new argument in all the output functions for 
everybody for such a seldom used feature. Isn't there another way to implement 
this?
