Subject: [dpdk-dev] DPDK/ipv4_mcast sample application doesn't work
Date: Mon, 6 Sep 2021 07:34:49 +0000	[thread overview]
Message-ID: <CS1PR8401MB09342B5CCA24520B55BE2452F5D29@CS1PR8401MB0934.NAMPRD84.PROD.OUTLOOK.COM> (raw)

Hi,
We are trying to use the ipv4_multicast app in DPDK examples.
However, we are not able to get it to run as expected.

The behavior that we are seeing is that packets are being sent from a packet generator but they are not being received by the APP. We have tried debugging the app by putting prints at various places but still don't have a clue on what is wrong.

We tried other examples apps like testpmd, l2fwd etc and these are working flawlessly.

Need inputs from the DPDK experts on the ipv4_multicast app.

Command used:


./<build_dir>/examples/ipv4_multicast -c 0x1 -n 1 -- -p 0x5 -q 2

DPDK Version: 20.08
NIC: XXV710 (fw version: 8.3)
Bound to: vfio-pci UIO


With the above command:

*       rte_eth_rx_burst() returns 0 in the ipv4_multicast app even when packets are being sent to the NIC/port.



Regards,
Rashmi.
