[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.
