The dsa_8021q_bridge_tx_fwd_offload_vid is no longer used just for bridge TX forwarding offload, it is the private VLAN reserved for VLAN-unaware bridging in a way that is compatible with FDB isolation. So just rename it dsa_tag_8021q_bridge_vid. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
