[Mo, YufengX] when size is beyon the range, dpdk-pdump won't boot up. Do you want to add a verification.

will it do the same verification for other range checking?

> Suggest add one case for jumbo frame packet capture, not sure whether jumbo frame should be validated here.

[Mo, YufengX]  Do you mean to write a new case for jumbo frame?

[Mo, YufengX] no things happen when total-num-mbufs changes. Currently, test case will reboot dpdk-pdump/testpmd

after each different option finish testing.

Within those email discussed with Reshma, she has mentioned that dpdk-pdump don't work for performance, you are are in

maillist too.
