This user space vhost library is based off user space vhost example and aims to
provide same API for different vhost implementations. This implementation
includes user space vhost cuse driver, kernel module for eventfd proxy and

Old vhost example consists of vhost cuse driver, virtio device management, and
VMDQ based packet switching logic.
vhost cuse driver and virtio device management are moved into vhost lib. This
patch modifies vhost example to use vhost lib API.
Huawei Xie (2):
copy main.c main.h from old vhost
packets to or receive packets from
guest virtio device. virtio_dev_rx/tx is removed.
5) zero copy feature is implemented in the example.
6) mergable rx/tx will be implemented in vhost lib.

main.c and main.h are refactored to become vhost lib in vhost lib patch, thus
are removed. Here they are copied back from old vhost example without any
modification.
