[fedora-virt] [PATCH 00/24] qemu-kvm: backport vhost net from upstream

[Michael S. Tsirkin]

The following patchset backports vhost net support
from qemu-kvm master to F13. I'd like the patches to
be added to fedora before feature freeze.

These patches are required for vhost net feature. Feature page here:
https://fedoraproject.org/wiki/Features/VHostNet

The patches have been posted upstream, and apply without changes.  Most
infrastructure is upstream already, and has been backported by simple
cherry-pick.

Thanks!
