I think it is OK to have the testpmd command (this patch), at least makes the 
'rte_eth_tx_done_cleanup()' API used, but I believe this is not the best/easiest 
way to verify relevant PMD implementation.


For long term though we should have the 'app/test/test_ethdev.c' and improve it 
gradually and collectively.
