This series brings some improvements to the cross-endian support in the
virtio and vhost code:
- use qemu_set_vnet_be() and qemu_set_vnet_le() directly from virtio-net,
so that backend cross-endian capabilities benefit to both emulated and
vhost accelerated devices
- optimize virtio_access_is_big_endian() for little-endian targets
- various cleanups
This v4 is a respin of the v3, taking into account the following fix:
commit cf0a628f6e81bfc9b7a944fa0b80c3594836df56

net: set endianness on all backend devices
It impacts patches 1 and 2, that had already been reviewed.
Laurent, Cornelia,
Could you please ack/nack the changes ?
The series is based on Michael Tsirkin's tree:

Thanks.
