  Modified files:
    sys/netinet          ip_demux.c 
  Log:
  Correct the th_off check against ip_len.  The check in ip_demux occurs
  before ip_len is adjusted so we have to add iphlen into the equation.  We
  forgot to do this when the code was originally moved from tcp_input to
  ip_demux (in tcp_input the check occurs after ip_len is adjusted).
  
  This fixes a panic assertion in tcp_input when a mangled packet is received.
