Let's take a look to ifconfig(8) manual page:
SYNOPSIS
ifconfig [-L] [-k] [-m] [-n] interface [create] [address_family] [address
[dest_address]] [parameters]
It states that "create" word may be used with address family,
adresses and other paramerets in line. Now there is design problem brought
into ifconfig code with sam's commit 2006/07/09. Current code
defers device cloning using callback facility because vlan creation
procedure needs to gather vlan tag and parent device parameners before.
However, it means that "create inet" or "create tunnel" clauses
now became incorrect. So this change broke things and should be corrected.
Basically, it broke all setups for sake of vlan processing.
It seems that vlans should be processed as special case leaving
all other cases in peace.
