Change Details

Preserve packet order between tcp_lro_rx() and if_input() to avoid creating extra corner cases. If no packets can be LROed, combine them into one change for submission via if_input(). If any packet can potentially be LROed however, retain old behaviour and call if_input() for each packet. This should keep the 12% improvement for small packet forwarding intact, but mostly avoids impacting the LRO case.
