The "ksz8795", "ksz9893", "ksz9477" and "lan937x" tagging protocols populate a bit mask for the TX ports. Unlike the others, "ksz9477" also accelerates HSR packet duplication. Make the HSR duplication logic available generically to all 4 taggers by using the dsa_xmit_port_mask() function to set the TX port mask.
