13.7.20FC Received Unsupported Count

FCRUC (04058h; R)

This register counts the number of unsupported flow control frames that are received.

The FCRUC counter increments when a flow control packet is received that matches either the reserved flow control multicast address (in FCAH/L) or the MAC station address, and has a matching flow control type field match (to the value in FCT), but has an incorrect opcode field. This register only increments if receives are enabled.

13.7.21Packets Received (64 Bytes) Count

PRC64 (0405Ch; R)

This register counts the number of good packets received that are exactly 64 bytes (from <Destination Address> through <CRC>, inclusively) in length. Packets that are counted in the Missed Packet Count register are not counted in this register. This register does not include received flow control packets and increments only if receives are enabled.
