virDomainDefCollectBootOrder() is called for every item on the list for each type of device. Since an <interface type='hostdev'> is on both the list of hostdev devices and the list of network devices, it will be counted twice, and the code that checks for multiple devices with the same boot order will give a false positive. To remedy this, we make sure to return early for hostdev devices that have a parent.type != NONE. This was introduced in commit 5b75a4, which was first in libvirt-4.4.0.
