Hello,


I have two Intel servers S2600WTTR and S2600WT2 both with 82599 10G
Ethernet Controllers

I run the same DPDK application on both servers.

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 ?


OS: RHEL 6.6 x86-64

DPDK: 16-07-rc1

S2600WTTR is working right?

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

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.

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.

I have the same problem on my 82599 nic, after I turnoff the jumbo_frame,
it works.
you can try rte_eth_dev_configure with the dev_conf.jumbo_frame = 0.
