The number of MAC control frames received by a port with 88-08h in
EtherType field.
The number of PAUSE frames received by a port. PAUSE frame is
qualified with EtherType (88-08h), DA, control opcode (00-01), data
length (64 byte min), and a valid CRC.
Rx good broadcast packets (not including errored broadcast packets or
valid multicast packets).
Rx good multicast packets (not including MAC control frames, errored
multicast packets or valid broadcast packets).
Rx good unicast packets.
Total Rx packets (bad packets included) that were 64 octets in length.
Total Rx packets (bad packets included) that are between 65 and 127
octets in length.
Total Rx packets (bad packets included) that are between 128 and 255
octets in length.
Total Rx packets (bad packets included) that are between 256 and 511
octets in length.
Total Rx packets (bad packets included) that are between 512 and
1023 octets in length.
Total Rx packets (bad packets included) that are between 1024 and
1522 octets in length.
Total Rx packets (bad packets included) that are between 1523 and
2000 octets in length.
Total Rx packets (bad packets included) that are between 2001 and
Max-1 octets in length (upper limit depends on max packet size ?1).
Tx hi-priority good octet count, including PAUSE packets.
The number of times a collision is detected later than 512 bit-times into
the Tx of a packet.
The number of PAUSE frames transmitted by a port.
Tx good broadcast packets (not including errored broadcast or valid
multicast packets).
Tx good multicast packets (not including errored multicast packets or
valid broadcast packets).
Tx good unicast packets.
Tx packets by a port for which the 1st Tx attempt is delayed due to the
busy medium.
Tx total collision, half-duplex only.
A count of frames for which Tx fails due to excessive collisions.
Successful Tx frames on a port for which Tx is inhibited by exactly one
collision.
Successful Tx frames on a port for which Tx is inhibited by more than
one collision.
