2014-06-19	Add the vhost-user netdev backend to the command line	Nikolay Nikolaev	1	-3/+106
	The supplied chardev id will be inspected for supported options. Only a socket backend, with a set path (i.e. a Unix socket) and optionally the server parameter set, will be allowed. Other options (nowait, telnet) will make the chardev unusable and the netdev will not be initialised. Additional checks for validity: - requires `-numa node,memdev=..` - requires `-device virtio-net-*` The `vhostforce` option is used to force vhost-net when we deal with non-MSIX guests.

2014-06-19	Add new vhost-user netdev backend	Nikolay Nikolaev	1	-0/+155
	Add a new QEMU netdev backend that is intended to invoke vhost_net with the vhost-user backend. It uses an Unix socket chardev to establish a communication with the 'slave' (client and server mode supported). At runtime the netdev will handle OPEN/CLOSE events from the chardev. Upon disconnection it will set link_down accordingly and notify virtio-net; the virtio-net interface will go down.
