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 ?
