Sorry, systemd will not parse any smbios code.

If these fields are generally useful, please add them as properties to
the sysfs device, and systemd can possibly read them.

Unrelated to the way we retrieve the information, the functionality
sounds out-of-scope for udev's rather simple netdev naming; and for
now, I see the simplicity rather as a feature than a limitation.
