Thank you for posting upstream.

All documentation i found found on the Xen wiki suggests that interfaces
are connected vifX.Y <-> ethY. [0] [1]
The only other way i know of for identifying the interfaces are MAC
Addresses which can be randomly assigned if you don't configure them.
I also checked which net_ids udev knows about and the only things that
pop up are:
ID_NET_NAMING_SCHEME=v247
ID_NET_NAME_MAC=enx00163efd832b
ID_OUI_FROM_DATABASE=Xensource, Inc.
Either i am missing the way you're supposed to do this, or there is a
bug somewhere in the toolchain.
Unfortunately i'm not able to pinpoint the source of the issue, any help
would be appreciated.
