Virtio_user for kernel interface.

[Carlos de Souza Moraes Neto]

Hello!
I'm attempting to utilize virtio_user for packet transmission and reception via the kernel's network stack. I transmitted packets from a NIC to virtio_user0 and captured them on the tap0 interface. However, when trying to send a packet from tap0 (for instance, a basic ping) and route it to DPDK, the function rte_eth_rx_burst returns zero packets. My initialization is set as follows: 
	-l 0-4 --vdev=virtio_user0,path=/dev/vhost-net,queues=3,queue_size=1024. 
With the forthcoming removal of KNI from DPDK, I have to rely on virtio but I cant find a way to use it as a bridge to the kernel stack and my dpdk app. I could not find any example or similar application for reference.

Sincerely,

Carlos Moraes
