I was doing some tinkering with the /dev/bpf device.

My understanding is that reading from the bpf device gives you a raw dump 
of the data over the network.

You will have a bpf header (18 bytes?)
Then I need to know the ip_offset for packets comming
in over the ed1 network interface so I can start calculating
how much traffic is going to what address based on the ip header.

Any help would be appreciated.
