e799b6e1ab Correct the parsing of the server IP address.
It's the address of the responding server, not the boot server. Which
makes sense, since there's another field for the boot server name.

178a83f3e0 Make pcap.Reader's API look like bufio.Scanner's.
The Next/Packet/Err structure makes read loops much
cleaner, and presents a more familiar interface for people
familiar with the stdlib.

67755cdc83 Add a basic pcap reader.
Very basic, it only parses the pcap structure to pull out the packets,
nothing more.

7f4b62d890 Drop the retransmit timeout on the lossy connection test.
Since this is a test to localhost, a 10ms RTO is more than enough,
and speeds up the test 10x.
