I'm on 6.12.x here and can't recall any changes in the naming of NICs by
the kernel for a while now. Have a quick read here:
https://wiki.gentoo.org/wiki/Handbook:X86/Networking/
Advanced#Variable_names_and_values
At least it should help you configuring your interfaces in an agreeable
naming fashion.
When I go to the link, it says there is no text on this page which is a message
I have never seen before.
