Memory Maps and Bit Descriptions
Rx FCS Errored Packets: The total number of packets received that
had a length (excluding framing bits, but including FCS octets) between
64 and 1518 octets (1522 for VLAN tagged packets), inclusive, but had
either a bad Frame Check Sequence (FCS) with an integral number of
octets (FCS Error) or a bad FCS with a non-integral number of octets
(Alignment Error).
Rx Jabber Packets: The total number of packets received that were
longer than 1518 octets (1522 for VLAN tagged packets) (excluding
framing bits, but including FCS octets), and had either a bad Frame
Check Sequence (FCS) with an integral number of octets (FCS Error)
or a bad FCS with a non-integral number of octets (Alignment Error).
Rx Code Error Counter: The total number of packets received that the
PHY asserted RX_ER during reception.
Rx Ingress FIFO Full Drop Counter: The total number of good or bad
packets received which were dropped due to Ingress FIFO full condi-
tion, i.e., lack of system resources.
Rx Unicast SA Mismatch Drop Counter: The total number of good
packets received which were dropped because they had a unicast
address which did not match the source address and which are not
Pause or Control Frames.
Note: This counter will not be incremented if the packet is also dropped
due to FIFO Full condition.
Tx Bytes Lo (Octets): The total number of octets of data transmitted
on the network (excluding framing bits/SFD or jam octets but including
FCS octets). This count does NOT include collided octets from collided
transmission attempts.
Note: The upper 8 bits of this 40-bit counter are accessed via Tx Bytes
Hi (Register 0x60C4).
Tx Packets: The total number of packets transmitted successfully.
Tx Undersize Packets: The total number of packets transmitted suc-
cessfully that were less than 64 octets in length (excluding framing bits,
but including FCS octets), had a good FCS, and were otherwise well
formed.
Note: Packets less than 64 octets but with a bad FCS are counted in
the Tx Fragment Packets counter.
Tx 64 Octet Packets: The total number of packets (including bad pack-
ets) transmitted successfully that were 64 octets in length (excluding
framing bits but including FCS octets).
