> Bridge's default_pvid adds a vid by default, by which we cannot add a
> non-vlan fdb entry by default, because br_fdb_add() adds fdb entries for
> all vlans instead of a non-vlan one when any vlan is configured.
>  # ip link add br0 type bridge
>  # ip link set eth0 master br0
>  # bridge fdb add 12:34:56:78:90:ab dev eth0 master temp
>  # bridge fdb show brport eth0 | grep 12:34:56:78:90:ab
>  12:34:56:78:90:ab dev eth0 vlan 1 static
> We expect a non-vlan fdb entry as well as vlan 1:
>  12:34:56:78:90:ab dev eth0 static
> To fix this, we need to insert a non-vlan fdb entry if vlan is not
> specified, even when any vlan is configured.
