! Rx MPA Packets – Missed Packet. This is a count of packets
intended for the router, but at the time, the router could not receive
the packet (usually due to the temporary lack of receive buffers).
! Rx DFR Packets – Deferred Packets. This is a count of incidents
where CRS (carrier signal lost) and COL both occur at the same
time. These two events happen simultaneously as a result of jabber
(produced by faulty networking equipment, usually NIC’s).
