Subject: libxl: use preferred syntax for network device creation with upstream qemu
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~10271

libxl: use preferred syntax for network device creation with upstream qemu

Markus Armbruster points out in <m3r582pzc1.fsf@blackfin.pond.sub.org>
on qemu-devel that this is the prefered syntax going forward. Using it avoid
needlessly instantiating a qemu "vlan" and instead creates a simply host end
point and device.
