New revision: 296455
URL: https://svnweb.freebsd.org/changeset/base/296455

Log:
  As reported on the transport@ and current@ mailing lists, the FreeBSD TCP
  stack is not compliant with RFC 7323, which requires that TCP stacks send
  a timestamp option on all packets (except, optionally, RSTs) after the
  session is established.

  This patch adds that support. It also adds a TCP signature option to the
  packet, if appropriate.
