Subject: [PATCH net-next 0/3] bonding: vlan handling changes

From: Nikolay Aleksandrov <Nikolay Aleksandrov nikolay@...hat.com>

Hi,
I've queued all of these patches to net-next since they're tightly related
and the bugs that get fixed are not critical, so it's better to soak the
changes a bit. Also I'd much rather fix this with the slave list change in.
If you decide that they need to be posted for -net, let me know.

Patch 01 - fixes vlan 0 addition/removal since when we have 8021q module
loaded it gets added to all network devices, this causes the bonding to
output false warnings, output tagged learning packets (though with 0 tag)
The fix is by denying the addition/removal of vlan 0 through the ndo_vlan
functions and do it ourselves in the bond's netdev event handler when a
vlan 0 is added/removed from a bonding device. Also a small comment fix
which adds the missing proto parameter.

Patch 02 - switches the bonding to the now standard vlan syncing functions
vlan_vids_add/del_by_dev() and removes the bonding specific ones.

Patch 03 - reverts vlan addition in case of bond_add_vlan failure because
otherwise we may get bad vlan refcounts in the slaves.

Best regards,
 Nikolay Aleksandrov

Nikolay Aleksandrov (3):
  bonding: fix vlan 0 addition and removal
  bonding: change the bond's vlan syncing functions with the standard
    ones
  bonding: unwind on bond_add_vlan add failure
