[PATCH net-next v4 1/2] net: xilinx: axienet: Report RxRject as rx_dropped

[Sean Anderson <sean.anderson@linux.dev>]

The Receive Frame Rejected interrupt is asserted whenever there was a
receive error (bad FCS, bad length, etc.) or whenever the frame was
dropped due to a mismatched address. 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.
