passt/test/perf/pasta_tcp
David Gibson 2320ac3349 Don't abbreviate ip(8) arguments in examples and tests 
ip(8)'s ability to take abbreviated arguments (e.g. "li sh" instead of
"link show") is very handy when using it interactively, but it doesn't make
for very readable scripts and examples when shown that way.
