That is to say, the rx copybreak function has been removed since then, but the related code has not been completely cleaned up. So the purpose of this patch is to clean up the remaining related code of rx copybreak.

So the fec_set_mac_address() does nothing and just returns zero when it is invoked in the fec_enet_init(). Actually, the MAC address is set into the hardware through fec_restart() which is also called in the fec_enet_init().

Namely, last_overflow_check, rx_hwtstamp_filter and base_incval. These unused members make the struct fec_enet_private a bit messy and might confuse the readers.
