The API rte_eth_dev_info_get() updated the parameter 'max_rx_pktlen' in 'struct rte_eth_dev_info' as 16384. But when I try transmission with multiple segments, I could not transmit more than 9732 bytes. I tried with testpmd and getting the same results.ie) couldn't transmit more than 9732 using testpmd. Is this a limitation or am I missing anything? Note : I tried with X540 card. I got 'max_rx_pktlen' as 15387 and I could transmit and receive upto 15387.
