>it looks it prints tx and rx counts in terms of number of packets and related status(error type of that droped packetr). but actually i need mbuf status which is associated with that interface. tx and rx cound is secondary part for me.. i would like to check memory leak if any, in my code.

KW: All TX count drops are handled by the applications as that number of packets placed on the TX ring is returned in the tx_burst call not in the PMD. On the RX side if the mbufs are not available to attach to the data then you can look at the mempool stats, but that is about it.
