No, I also thought so, but it actually does not. I'm working here on
5.12.11, but there should not be any difference. It needs: if (vid >
1). Just tried it with (vid > 0) but then it does not work.

I really like your fix on wifi roaming, it works nicely. However I
found, still after this patch, it sadly does not work on vlan > 1. At
least it does not on 5.12.11 (the 'self' entry does not get removed
automatically, but after manual remove the client connects ok). I need
to go 5.14 one of these days because I just read DSA has a major
update. Then I also move from ubuntu focal to a more recent version.
Then I'll try wifi roaming on vlan again.
