SVN rev 215726 on 2010-11-22 23:35:29Z by zec
Allow for vlan(4) ifnets to have overlapping unit numbers if they are
created in separated vnets. As a side-effect of having a separated
if_cloner instance for each vnet, all vlan ifnets created in a vnet
will be automatically destroyed when vnet teardown is initiated.
Disallow SIOCSETVLAN and SIOCGETVLAN ioctls on vlan ifnets which are
associated with physical ifnets residing in parent vnets.
This is an interim vlan-specific solution which will be superseded by a
more generic if_cloner V_irtualization change from p4. For nooptions
VIMAGE builds, this should be a no-op change.
