Main issue to flag is that we expect most common clients to not have root access / raw socket support, which will limit the ability of the client to control fragmentation / sending behavior.

A test helper can be privileged and change semantics at this layer in responses back to a client, and learn about the DPI behavior in the Server->Client direction.

See measurement-kit/measurement-kit#1522 for a possible implementation of this concept. Given that we're moving towards a Go engine, measurement-kit/measurement-kit#1522 will not ever be merged in MK. Therefore, I'm linking it here, so we do remember about its existence, and then I'm going to proceed with closing the PR.
