ARCnet does not support multicast, only unicast and broadcast. In spite of this, the com20020 driver contains several references to multicast in a comment and a function name, including a FIXME that it should be implemented. Adjust the comment to make the lack of multicast support clear and rename com20020_set_mc_list to com20020_set_rx_mode.
