    sys/netinet          tcp_syncache.c tcp_var.h 
  The tcp syncache code was leaving the IPv6 flowlabel uninitialised
  for the SYN|ACK packet and then letting in6_pcbconnect set the
  flowlabel later. Arange for the syncache/syncookie code to set and
  recall the flow label so that the flowlabel used for the SYN|ACK
  is consistent. This is done by using some of the cookie (when tcp
  cookies are enabeled) and by stashing the flowlabel in syncache.
