Hi Ian
I suspect for 4.4.0, the network devices even was not detected.
this is output from 4.3.1, notes follow lines.

libxl: debug: libxl_device.c:959:device_hotplug: calling hotplug
script: /etc/xen/scripts/vif-bridge online
dlan: vif-bridge start
dlan: vif-common start

dlan: vif-bridge start -> output from vif-bridge script
dlan: vif-common start -> output from vif-common.sh script
