Andre Oppermann b2828ad291 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.
