A subsequent patch to add support for setting linkspeed/duplex in
virtio-net, requires a few definitions from ethtool.h, which ends up
pulling in kernel.h and sysinfo.h as well.

Hi,
Linux can now read linkspeed and duplex settings as set by the
hypervisor:
faa9b39 virtio_net: propagate linkspeed/duplex settings from the hypervisor
This series thus adds qemu support.
Also, this patchset depends on this header sync:
https://lists.gnu.org/archive/html/qemu-devel/2018-02/
In prepartion for using some of the high order feature bits, make sure that
virtio-net uses 64-bit values everywhere.

Although linkspeed and duplex can be set in a linux guest via 'ethtool -s',
this requires custom ethtool commands for virtio-net by default.
Introduce a new feature flag, VIRTIO_NET_F_SPEED_DUPLEX, which allows
the hypervisor to export a linkspeed and duplex setting. The user can

Start the free page optimization after the migration bitmap is
synchronized. This can't be used in the stop© phase since the guest
is paused. Make sure the guest reporting has stopped before
synchronizing the migration dirty bitmap. Currently, the optimization is
added to precopy only.
