sys/netinet : tcp_input.c
Log message:
Only accept simple TCP timestamp options for softlro.
Instead of parsing all TCP options, consider only two cases. No
options or only timestamps at aligned position. The latter is the
common case which must be fast. Ignoring other packets with
complicated options will not decrease speed.
In tcp_softlro_check() only packets without options or simple
timestamps are considered for LRO. Enforce that timestamps are
increasing to detect sequence number wraparounds. When concatenating
TCP packets, take the timestamps from the tail which are more recent.
