- This seems i40e specific, please move to drivers/net/i40e/i40e_testpmd.c.

- Besides, I would prefer that something in the command name clearly
states this is driver (here, i40e) specific.
Like "port config XX i40e_src_prune" or maybe the other way around,
start with a "driver i40e" prefix.

Maybe others have an opinion.
