Hello All,
We are trying to test virtio-vhost-kni performance,
I able to start kni application but after that when i looked for
/sys/class/net/vEth0, there's no sock_fd and sock_en parameters, hence i am
stuck from attaching fd to virtio-qemu.
Host: Fedora 23
HugetblsFS: 1G pages
Following is my config.
[root at localhost dpdk-2.2.0]# ./tools/dpdk_nic_bind.py --status

As this is sysfs, it has to be in kmod, but i don't see any mention of
these two parameters, what's going on?
Any help on what causes this issue?
-thanks-
