Hello,

In vhost-switch, it judges if a virtio device is ready for processing after
receiving
a pkt from virtio device. So you'd better construct a pkt, and send it out
firstly
in l2fwd.

I tried to ping the socket interface from host for the same purpose
but it didn't work.

Could you please suggest some other approach for achieving same(how
pkt can be sent out to l2fwd)?

Also, before trying this, I have verified that vhost-switch is working
ok with testpmd .

Thanks,
Amit.
