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.
