These packets are not been queued in the tx descriptors, the function 'rte_eth_tx_burst' is returning the less than n. So questions are following i) are there any issues seen ? Observations in our case :- i) packets are dropped and tx packets donot get incremented. ii) i) happens for 30 secs after that it recovers. iii) After sometime we see this issue in i) & ii) again. Any clues / pointers will help. Thanks, Regards, Venu
