Comment 3 for bug 1565561

The code extracting VLANID and IF_VLAN_RAW_DEVICE seems overly complex IMHO. The "case" statement already ensures we operate on vlan device so I think something much simpler would work:

  VLANID=`echo $IFACE|sed "s/[^.]\+\.\([0-9]\+\).*/\1/; s/^0//"`
  IF_VLAN_RAW_DEVICE=`echo $IFACE|sed "s/\([^.]\+\)\.[0-9]\+.*/\1/"`

This is also easier to read.
