The application works with one interface bound to physical or virtual PCI function depending on configuration The S2600WTTR server receives incoming traffic on physical and virtual functions The S2600WT2 server receives traffic only on physical function When I bind S2600WT2 VF to ixgbevf driver and configure it as Linux ETH interface, it works normally. Network sniffer shows that Ethernet frames arrive to S2600WT2 port and frames are valid, however DPDK does not receive them. Where can I start to debug this issue ?

But when the same VF is bound to ixgbevf driver and configured as Linux interface, it works normally. I was able to run ping and ssh through that VF. So my guess is that the RX issue is not due to malfunction hardware. The same binary works correctly on S2600WTTR server with 82599 VF I also tested the application with Mellanox ConnectX-4 on both servers There were no issues with CX-4 PF and VF For some reason DPDK VF RX functionality does not work on S2600WT2.
