ip6_pol_route panic: Do not allow VLAN on loopback
Several tests in the ipv6 routing code check IFF_LOOPBACK, and
allowing stacking such as VLAN'ing on top of loopback results in a
netdevice which reports IFF_LOOPBACK but really isn't the loopback
device.
Instead of spamming the ipv6 routing code with even more special tests,
simply disallow VLAN over loopback.
The result of this patch is:
# modprobe 8021q
# vconfig add lo 43
ERROR: trying to add VLAN #43 to IF -:lo:- error: Operation not supported
