[Merge] ~rbalint/ubuntu/+source/systemd:ubuntu-focal-lp1870410 into ~ubuntu-core-dev/ubuntu/+source/systemd:ubuntu-focal

[Balint Reczey]

It fixed wifi on my rpi2 with external wifi dongle and is unlikely to cause regressions.

I'm looking into not calling link_configure multiple times or at least skipping bigger parts of the configuration before forwarding this upstream.
