Subject: [PATCH net-next 06/15] net: dsa: sja1105: allow VLAN configuration from the bridge in all states

From: Vladimir Oltean <vladimir.oltean@....com>

Let the DSA core call our .port_vlan_add methods every time the bridge
layer requests so. We will deal internally with saving/restoring VLANs
depending on our VLAN awareness state.
