Hi all,
I have a problem with the configuration of the sample application l3fdw for
switching traffic between two vhost-user NICs, each with 4 queues. The
traffic was generated using TREX, running inside a VM.
When I traced my experiment, I noticed that the traffic was only received
in queue "0", while the other RX queues were empty. When I run the
application, a msg is printed "Port 1 modified RSS hash function based on
hardware support,requested:0xa38c configured:0".
It seems that while the vhost-user NIC implementation supports multiple
queues, it does not support distributing the traffic between the RX queues.
I wonder if there is a way to make it work?
Thank you,

Does your traffic have multiple 5 tuple flows to distribute it across multiple Rx queues?
