[Qemu-devel] [PATCH V4 00/12] Add COLO-proxy virtio-net support

[Zhang Chen <zhangchen.fnst@cn.fujitsu.com>]

If user use -device virtio-net-pci, virtio-net driver will add a header
to raw net packet that colo-proxy can't handle it. COLO-proxy just
focus on the packet payload, so we skip the virtio-net header to compare
the sent packet that primary guest's to secondary guest's.

V4:
 - Add vnet_hdr option for filter-mirror, filter-redirector,
   filter-rewriter,colo-compare.
 - Use new design to impliment virtio-net support for colo-proxy.
 - Fix codestyle.
 - Remove unused option for filter-rewriter.
 - Add filter-rewriter virtio-net support.
 - Address other comments.
