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 Ethernet controller’s on-chip transmit buffer. Note that this 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.

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 can be caused by excessive collisions or PAYLEN errors. This 
register only increments if transmits are enabled.
