Gang, some comments below. Please split test suite and test plan into two patches. 
It will be more easily for review and I just reviewed test plan in your patch.

I think Lei is working on this issue. Please remove it from your patch.

Please separate test plan and test suite. It will be more easily for review.

Please keep "=" align with case name.

You can remove target, everyone known how to start testpmd application.

SSH login action will be done by automation script, you can just add one comment "Login into XXX".

Please give some basic description for the command, like start vm using hugepage backend memory + one vhost-user netdev (merged buf on, multiqueue on).

And not need to show precise qemu path, everyone known how to find qemu binary in their own environment.

Typo issue, should be "Vhost".

Should be step 6 and 7. You can just remove the index.

Case name is redundancy, you can simplify it like "Performance comparison on vector path"

Clear function should workable on every kinds of statistics. You can add clear function check in test1 and test2, and remove this case.
