    bridge: Fix inability to add non-vlan fdb entry · 25d3b493
    Toshiaki Makita authored
    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.
