Meijuan,
Please naming test case with same format, we'd like to use meaningful sentence for test case name.
Eg. This case name will be better like "dpdk VF packet IO with kernel PF".

Please remove duplicated header in this test plan, you can move second line into test description.
And I think this information can be included in test case name like "dpdk VF reset with kernel driver PF".
