    sys/netinet          in.h in_pcb.h ip_output.c raw_ip.c 
  Implement IP_DONTFRAG IP socket option enabling the Don't Fragment
  flag on IP packets.  Currently this option is only repected on udp
  and raw ip sockets.  On tcp sockets the DF flag is controlled by the
  path MTU discovery option.
  Sending a packet larger than the MTU size of the egress interface
  returns an EMSGSIZE error.
