tcp-testsuite into src?

[Kevin Bowling]

Hi,

I was talking with gnn and kevans on IRC about the tcp testsuite
(https://github.com/freebsd-net/tcp-testsuite).

Currently we maintain this in ports, although the way the port is set
up doesn't make a lot of sense because the tests are stack specific
and we don't account for different FreeBSD versions let alone vendor
trees.  It seems reasonable to me to pull the tests themselves (i.e.
https://github.com/freebsd-net/tcp-testsuite) into src where they can
follow along with the tree they are running on, and provide vendors a
natural point of extension.

/usr/tests has some existing examples of relying on out of tree
binaries to run so I am not convinced we need to import packetdrill
itself but I don't have a strong preference.  tuexen, do you have any
preference?

Regards,
Kevin
