Yep, I remember that discussion, though from my impression
(probably wrong) people talked more about need for some smart
testpmd plugin approach.
I didn't realize that it would mean literally dump all
current cmd-line related code straight into drivers/net.
I agree that testpmd code for PMD-specific API should be
responsibility of this PMD maintainer.
I just don't feel that drivers/net is the best place for it.
As another thing to consider: what would happen if we'll decide
to rework testpmd interface (from CLI to gRPC or so), or introduce
new app for PMD testing - would we need to inject all these things
into drivers/net too?
