Looking closer, this:

# ok 3 - mptcp[...] MPTCP # time=7184ms
# ok 4 - mptcp[...] TCP   # time=6458ms

Makes NIPA unhappy. The match results for regexps look like this:

(None, '4', ' -', 'mptcp[...] MPTCP', ' # ', 'time=6173ms')
(None, '4', ' -', 'mptcp[...] TC', None, 'P   # time=6173ms')

IOW the first one is neat, second one gepooped. The regex really wants
there to be no more than a single space before the #. KTAP definition
doesn't say that description must not have trailing white space.

Best I could come up with is:

diff --git a/contest/remote/vmksft-p.py b/contest/remote/vmksft-p.py
index fe9e87abdb5c..a37245bd5b30 100755

     time_re = re.compile(r"time=(\d+)ms")

     for line in full_run.split('\n'):

Thoughts?
