This series make filters and colo-compare module support vnet_hdr by
default. And also support -device non-virtio-net(like e1000.) at the same time.
It can adapt -device automatically to avoid wrong setting between
different filters when enable/disable virtio-net-pci. So no need to keep the
"vnet_hdr_support" flag in filter's property.
Optimize the filter transfer protocol from:
1.size -----> 2.real network payload.
to:
1.size -----> 2.vnet_hdr_len. -----> 3.real network payload.
When receiving node get the network packet, it will compare with
the local vnet_hdr_len. If they are not the same, report a error.
because this kind of packet cannot be correctly parsed by receiving
node. For the colo-compare, it need to compare whether the two sides
vnet_hdr_len are equal.
v4:
Rewrite patches to impliment it in filter transfer protocol payload.
Remove filters and colo-compare's "vnet_hdr_support" flag.
v3:
Fix some typos.
Rebased for Qemu 6.2.
v2:
Detect virtio-net driver and apply vnet_hdr_support
automatically. (Jason)
