Merge branch 'VLAN-fixes-for-Ocelot-switch'
Vladimir Oltean says: ==================== VLAN fixes for Ocelot switch This series addresses 2 issues with vlan_filtering=1: - Untagged traffic gets dropped unless commands are run in a very specific order. - Untagged traffic starts being transmitted as tagged after adding another untagged VID on the port. Tested on NXP LS1028A-RDB board. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
