New vhost example is a transform of old vhost example.
It calls vhost library API to receive/transmit packets from guest VM.
zero copy logic is kept in vhost example.
Huawei Xie (14):
copy old vhost example files main.c/main.h as the base of new vhost example
remove virtio_dev_(merge_)rx
This patch copies two files main.c/main.h from most recent vhost example as
