Lihong,
Please simplify the name of each test case.
You can remove words "DPDK" and "function" from the case name.
It's also no need to add index of in the case name.

Sample:

Test Case: PVP virtio-pmd queue number dynamic change
Test Case: vhost pmd/virtio-pmd PVP 2queues mergeable path performance

Thanks,
Marvin
