  SVN rev 215871 on 2010-11-26 15:46:49Z by zec
  
  MFC r215726:
  
    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    This is an interim vlan-specific solution which will be superseded by a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.
