Commit 8ad227ff89a7e6f05d07cd0acfd95ed3a24450ca ("net: vlan: add
802.1ad support") added some new NETIF_F_* features bits, but it
added them in the middle of existing values.
Userland depends upon the flag bits via the per-netdevice 'flags'
sysfs file.
So restore the previous ordering by adding the new flags at the
end.

Linus, just apply this to your tree directly if it works for you.
It obviously should since this is essentially what you tested already.
Thanks.
