The 'dsa_tag_8021q_bridge_join' could be used as a generic implementation of the 'ds->ops->port_bridge_join()' function. However, it is necessary to synchronize their arguments. This patch also moves the 'tx_fwd_offload' flag configuration line into 'dsa_tag_8021q_bridge_join' body. Currently, every (sja1105) driver sets it, and the future vsc73xx implementation will also need it for simplification.
