Re: [dts] [PATCH V1] Add sw eventdev test plan

No, all the evendev cases are performance related, after talking with harry, he think the result got by a low speed traffic generator is meaningless.

Yuwei,
Please add some descriptions in the header of the test plan.
I saw that all test cases depend on IXIA. Could we make those cases suitable for software packet generator like scapy?
Not everyone has expensive hardware instrument. For those who just want to check the basic status of eventdev, few thousands of packets are enough. 

Thanks,
Marvin
