IPv6Packet is used to construct IPv6 Packets. They contain an EthHeader and an IPv6Header, and in the distant, unknowable future, will take interesting IPv6ish payloads.

This mostly complete, but not very useful. It’s intended primarily as an example protocol.

Parameters

  :eth
    A pre-generated EthHeader object.
  :ip
    A pre-generated IPHeader object.
  :flavor
    TODO: Sets the "flavor" of the IPv6 packet. No idea what this will look like, haven't done much IPv6 fingerprinting.
  :config
    A hash of return address details, often the output of Utils.whoami?
