udev: link_setup - respect kernel name assign policy Newer kernels export meta-information about the origin of an ifname. Respect this from the ifname rename logic. We do not rename any interfaces that was originally named by userspace, nor once which have already been renamed from userspace. Moreover, we optionally do not (the default) rename interfaces which the kernel claims to have named in a predictable way.

udev: net-config - allow interface names to be set from the hwdb

network: move configuration to /etc/systemd/network This is private configuraiton, so let's not pollute the namespace (and hence make Debian happy :) ).
