This counter is incremented for each packet
received with a Frame Check Sequence
error (bad CRC).
This counter is incremented for each
receive aborted due to data or status FIFO
overruns (insufficient buffer space).
This counter is incremented for each packet
received with a Frame Alignment error.
This counter is incremented for each packet
received with one or more 100 Mb symbol
errors detected.
This counter is incremented for each packet
received with greater than the 802.3
standard maximum length of 1518 bytes.
Packets received with In Range Length
errors. This counter increments for packets
received with a MAC length/type value
between 64 and 1518 bytes, inclusive, that
does not match the number of bytes
received. This counter also increments for
packets with a MAC length/type field of less
than 64 bytes and more than 64 bytes
received.
Packets received with a valid MAC control
type and an opcode for a function that is not
supported by the device
MAC control Pause frames received.
The byte count of each successfully
transmitted packet is added to this counter.
The packet byte count includes the address,
type, data, and FCS fields.
This counter is incremented for each packet
successfully transmitted. This count
includes broadcast, multicast, and physical
address packets.
This counter is incremented for each packet
transmission which is deferred due to active
line conditions (once per packet).
This counter is incremented for each
broadcast packet successfully transmitted.
This counter is incremented for each
multicast packet successfully transmitted.
This counter is incremented for each packet
successfully transmitted with 1 in-window
collision.
This counter is incremented for each packet
successfully transmitted with 2-15 in-
window collisions.
MAC control Pause frames transmitted.
