Hi,
I have observed packet loss with usvhost dpdk interfaces even at a very
small rate .
This is because virtqueue [dev->virtqueue] is found to be full,
and my application should drop the packets .
some one pls help me ,
how can I avoid this loss .
--------
thanks
srinivas.

Maybe your virtio guest is slow in processing the packets.
Could you refer to the retry mechanism in the vhost example? search
enable_retry in switch_worker in examples/vhost/main.c.
