Well, running the existing tests (and your own use cases) fine are of course
a very good start and a precondition for the code to get accepted.

I haven't read up on the details on how this TFTP negotiation is being done,
but in general the test servers don't necessarily have to be that clever, to
actually support "the real thing". They merely need to have a way to send
custom things and record what it gets back, and then we can make up test cases
that make the server send the right things and make sure the client (curl)
deals with it fine, but we can also make sure the server sends the _wrong_
thing and verify the client in that aspect as well.

It's certainly not _necessary_, only a good thing to make sure the
functionality is there, is solid and will remain so when things change ahead.

I'm glad to hear the patch is near arrival!

I'd say the patch should be separated into two separate ones to make them
easier to digest and review! Please send over the libcurl patch once you have
something you want reviewed/applied and we'll have a look. With the TFTP
negotiation code in place, the chances of someone else helping out with
getting it tested by the test suite also increases!
