    sys/netinet          tcp_subr.c 
  In TCP notify routines, check inpcb for INP_TIMEWAIT and INP_DROPPED.
  The INP_DROPPED check replaces the current NULL checks; the INP_TIMEWAIT
  checks appear to have always been required, but not been there, which
  is/was a bug.  This avoids unconditionally casting of in_ppcb to a tcpcb,
  when it may be a twtcb, which may have resulted in obscure ICMP-related
  panics in earlier releases.
