So you read the date from the buffer and just discard it?
Are you going to miss messages this way?
Please clarify.

Christofer, have you measured the network performance difference with KVM.
Probably the next patchseries (with IRQFD) makes bigger difference.
In any case, sharing some numbers will be great.
Thanks.

Vhost-user will implement the multiqueueu support in a similar way to what
vhost already has - a separate thread for each queue.
To enable multiquue funcionality - a new command line parameter
"queues" is introduced for the vhost-user netdev.

qemu_get_ram_fd doesn't accept a guest physical address. ram_addr_t are
opaque values that are assigned in qemu_ram_alloc.
Find the ram_addr_t corresponding to the userspace_addr using
qemu_ram_addr_from_host,
and then call qemu_get_ram_fd on it.

This will set an array of file descriptors to the internal structures.
The next time a message is send the array will be send as ancillary
data. This feature works on the UNIX domain socket backend only.

This extends the existing qemu_chr_fe_get_msgfd by allowing to read a set
of fds. The function for receiving the fds - unix_process_msgfd is extended
to allocate the needed array size.

This document describes the basic message format used by vhost-user
for communication over a unix domain socket. The protocol is based
on the existing ioctl interface used for the kernel version of vhost.

Decouple vhost from the Linux kernel by introducing vhost_ops. The
intention is to provide different backends - a 'kernel' backend based on
the ioctl interface, and an 'user' backend based on a UNIX domain socket
and shared memory interface.
