    sys/netinet          tcp_syncache.c 
  Comment out the syncache's test which ensures that hosts which negotiate TCP
  timestamps in the initial SYN packet actually use them in the rest of the
  connection.  Unfortunately, during the 7.0 testing cycle users have already
  found network devices that violate this constraint.
  RFC 1323 states 'and may send a TSopt in other segments' rather than
  'and MUST send', so we must allow it.
