0 IP header checksum generation is disabled even if enabled in a transmit frame control block.
1 IP header checksum generation is performed for IPv4 headers as determined by the settings in the
TCP/UDP header checksum generation enable. When set, the eTSEC offloads TCP or UDP header
checksum generation. See

pause control frame with the duration value obtained from the PTV register. The TXC event occurs after
sending the pause control frame. Finally, the controller clears TFC_PAUSE and resumes transmitting
data frames as before. Note that pause control frames can still be transmitted if the Tx controller is
stopped due to user assertion of DMACTRL[GTS] or reception of a PAUSE frame.
