Subject: Re: [dpdk-dev] No RX frames on Intel 82599 VF
Hi,
On the S2600WT2 server, when DPDK is bound to VF, there is no incoming traffic.
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.
[Wenzhuo] No clue now. But I think you can compare what’s the difference between S2600WT2 and S2600WTTR.

S2600WTTR is working right?

Don't understand what you're doing here. And you say *works*? Is S2600WT2 the one not working?
