[Iftop-users] Add traffic accounting in PPS; drop short packets

[fred at fperrin.net]

Hi list,

I'm sending the following patches. The first is a one-liner gcc was
complaining about; the second add a new feature to do traffic
accounting in packet per second rather than bit/s; the third is a fix
to handle_ip_packet() which was reading past the end of certain
malformed packets.

[PATCH 1/4] Silence a warning
[PATCH 2/4] Do traffic accounting in pps
[PATCH 3/4] Drop packets shorter than sizeof (struct iphdr)
