The code that we have that writes the initial network configuration
that maps mac addresses <-> device names  (so that we handle modules
loaded in arbitrary order) associates network devices with physical
devices by following net:XXXX symlinks in /sys/bus/pci/devices/XXX,
/sys/bus/pcmcia/devices/XXXX, /sys/bus/xen/devices/XXX, etc.

The new code (that removes those links) breaks this hard, and
rearchitecting everything to have a second pass that walks /sys/class/net/XXX
links and associates them with already probed/discovered devices
is not something I'm doing at this stage of the freeze.
