So I did a git bisect from linux-v5.10 (good) to linux-v5.14.11 (bad).

The result was:

dilfridge /usr/src/linux-git # git bisect bad
6381195ad7d06ef979528c7452f3ff93659f86b1 is the first bad commit
commit 6381195ad7d06ef979528c7452f3ff93659f86b1
Author: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Date:   Mon May 24 17:26:16 2021 +0200

    ACPI: power: Rework turning off unused power resources
[...]

I tried naive reverting of this commit on top of 5.14.11. That applies nearly cleanly, 
and after a reboot the additional ethernet interfaces show up with their MAC in the
boot messages.

(Not knowing how safe that experiment was, I did not go further than single mode and
immediately rebooted into 5.10 afterwards.)
