This register counts the number of multicast packets transmitted. This register does
not include flow control packets and increments only if transmits are enabled. Counts
clear as well as secure traffic.
Broadcast Packets Transmitted Count - BPTC (0x040F4; RW)
This register counts the number of broadcast packets transmitted. This register only
increments if transmits are enabled. This register counts all packets, including standard
and secure packets. Management packets are never more than 200 bytes.
TCP Segmentation Context Transmitted Count - TSCTC (0x040F8; RW)
This register counts the number of TCP segmentation offload transmissions and
increments once the last portion of the TCP segmentation context payload is
segmented and loaded as a packet into the on-chip transmit buffer. Note that it is not a
measurement of the number of packets sent out (covered by other registers). This
register only increments if transmits and TCP segmentation offload are enabled.
TCP Segmentation Context Transmit Fail Count - TSCTFC (0x040FC;
RW)
This register counts the number of TCP segmentation offload requests to the hardware
that failed to transmit all data in the TCP segmentation context payload. There is no
indication by hardware of how much data was successfully transmitted. Only one failure
event is logged per TCP segmentation context. Failures could be due to Paylen errors.
This register will only increment if transmits are enabled.
Interrupt Assertion Count- IAC (0x04100; R)
This counter counts the total number of interrupts generated in the system.

Number of broadcast packets transmitted count.
Number of TCP Segmentation contexts transmitted count.
Number of TCP segmentation contexts where the device failed to
transmit the entire data payload.
This is a count of the Legacy interrupt assertions that have occurred.
