Hi Bruce,

Could not get it working by disabling the vector PMD, Do you have any
example where it works?

Thanks,
Mohan

Hi,

I have tried this and it does not work

What type of NIC are you using. If you are using ixgbe or i40e, try
disabling
the vector PMD in your build-time configuration to see if it makes a
difference.

However, why do you want to receive just a single packet at a time. Why
not just
receive a burst of packets and then process them one at a time? It's much
more
efficient that way, and you should get better performance from your
application.

Hi,

Is there any option to receive single packet at a time with dpdk?

Not sure if this is the answer you are looking for, but if you just
request a single packet with

struct rte_mbuf *mbuf;
rte_eth_rx_burst(port_id, queue_id, &mbuf, 1);

will return only one packet as a time.
