====================
mlxsw: add offload support for vlan_filtering option

Elad says:

This patch adds SWITCHDEV_ATTR_ID_BRIDGE_VLAN_FILTERING port attribute.
When a bridge is offloaded to hardware, the hardware can learn if the bridge is
.1Q bridge (VLAN-aware) or not VLAN aware bridge.
In order to toggle the mode a user can use sysfs:
$ echo 1 > /sys/devices/virtual/net/br0/bridge/vlan_filtering
or via iproute2:
$ ip link set dev br0 type bridge vlan_filtering 1
