I am using I350 card. 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.
