Follow-up Comment #7:

I don't think we need to implement path discovery in icmp4 input.

It's done in IPv6 because it's mandatory, as routers can't fragment v6
packets.

I'm suggesting outgoing destination unreachable if we are unable to fragment,
or if DF is set (IPH_OFFSET(iphdr) & IP_DF). Or at least respect DF and
silently drop in this last case.
