Subject: [PATCH v2 net-next 1/1] tools: tc-testing: Add notap option

Add a command line arg to suppress tap output.  Handy in case
all the tap output is being supplied by the plugins.

Signed-off-by: Brenda J. Butler <bjb@...atatu.com>
---

v2:  Drop the first patch that changes the format
     of the tap output.  The second "notap" patch is
     reworked to apply cleanly without the first patch.
