To: dts; +Cc: Ding Heng
l3fwd: comment 2 cases no need to run in nightly performance test. Fix issues
for run rfc2544 case with different nic. Add 72 byte for performance test.
testpmd: change report format for generate nightly performance test. Use core
mask instead of all cores for performance test.
framework/pmd_output: optimize command for performance, run testpmd in vector
mode instead of Xmit mode. Optimize core configuration for testpmd because run
testpmd with all cores will get a bad performance result.

Please not changed this default value for other suites depend on this. You can appoint this value in performance suite.

That's strange logic, please change input core setting as required.

Please not changed this default value for other suites depend on this. You can appoint this value in performance suite.

That's strange logic, please change input core setting as required.
[Qian] Yes, I am also confused first to see it, I know the cores setting about 2C is testpmd used cores since testpmd will have a master core will is not used in packet fwd. So, you can name different, such as testpmd_cores and fwd_cores.
