some sample code took me some time about dpkt HOT 3 CLOSED

problems: wireshark/tcpdump will decode, but see checksum on cdp as incorrect. Next
step is to add more CDP fields, with the ultimate goal to be able to impersonate a
Cisco phone. Most Cisco Voip implementations depend on CDP messages to place phones
in a special VOIP vlan....

Final comment: eth_aton function stolen from http://zeaster.blogspot.com/ , but rest
of his sample code I can't get to work. He calls whole class (ip_p = ip.IP()...
packet.data = ip_p) which errors out for me. I find you have to call {packet
type}.pack() or a variation of {packet type).str or (packet type).data depending
on what you are doing. Also when programming this {packet type}.dict is uber
helpful to keep track of what class attributes are necessary.

We have example code on https://dpkt.readthedocs.io/en/latest/examples.html, if we have a targeted (packet injection for example) then we'll take PRs for those.
