Function update_tcp_header

dpdk/lib/gso/gso_common.h:74–86

* Internal function which updates the TCP header of a packet, following * segmentation. This is required to update the header's 'sent' sequence * number, and also to clear 'PSH' and 'FIN' flags for non-tail segments. * * @param pkt * The packet containing the TCP header. * @param l4_offset * The offset of the TCP header from the start of the packet. * @param sent_seq * The sent sequenc

 *  Indicates whether or not this is a tail segment.
