Currently I have an issue in a pass-thorugh mode. I am running in multi process (2 processes) via ixgbe_rxtx. When running with a single process I have a perfect traffic while with 2 processes I have no traffic at all. 
Perhaps there is a special configuration for that, can you please assist ?

Thanks
Yan
