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.
