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 packe= t generator but they are not being received by the APP. We have tried debug= ging the app by putting prints at various places but still don't have a clu= e 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: .//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 pa= ckets are being sent to the NIC/port. Regards, Rashmi.
