So this is really a combination of rx_otherhost_dropped, rx_length_errors, rx_frame_errors, and rx_crc_errors. Mismatched addresses are common and aren't really errors at all (much like how fragments are normal on half-duplex links). To avoid confusion, report these events as rx_dropped. This better reflects what's going on: the packet was received by the MAC but dropped before being processed.
