I've tried TX. It's working fine.
I'm sure problem is only with my code.

Which NIC are you using?
Have you tried dpdk-testpmd or l2fwd on your setup to check if the packet can be sent and received correctly?

External email: Use caution opening links or attachments

hello,

I'm trying to capture packets using the following piece of code :

==========================================================
struct rte_eth_rxconf rxq_conf = dev_info.default_rxconf;
rxq_conf.offloads = port_conf.rxmode.offloads;
rte_eth_rx_queue_setup( 0, 0, num_of_pkts_per_queue, (unsigned int)sock, &rxq_conf, mem_pool );
rte_eth_dev_start( 0 );
while( 1 )
{
num_of_pkts_rcvd = rte_eth_rx_burst( 0, 0, mbuf, num_of_pkts_per_queue );
fprintf( stderr, "num_of_pkts_rcvd: %u\n", num_of_pkts_rcvd );
}
==========================================================
It's always printing num_of_pkts_rcvd as 0.

Can someone help me understand what the issue is ....

Thanks & Regards
