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

Excuse me, I don't understand the relation between your question and the
patch below. If there is no relation, please open a new thread by clicking
on "new mail" instead of "reply all".

Maybe that some kind developers will help you but you'd have more chances
by providing your command line and more debug details showing that you tried
to debug it by yourself and you are not a lazy developer.

Re: [PATCH v2] virtio: Update max RX packet length

[Yan Freedland]

Hi, 

I mistakenly pressed on reply all instead of reply and sent my question to the whole dev. Sorry about that.
In fact I am not lazy and looks like I solved the problem by myself. I will gladly share my knowledge with you or anyone in dev and of course open a new mail thread with an appropriate subject for further appeals.

Thank you,
Yan
