Hi Vivien
As Florian pointed out, this cannot be changed. It is now part of the
ABI. We have to live with it printing little endian numbers as big
endian.

Rather than recommending something, it might be better to point to the
Free Desktop "Predictable Network Interface Names" which is what most
people will end up with, if they rename:
https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/
It would also be good to test on a recent systemd system and see what
happens. What names does it pick?
