I see. Afact it is a udev rule which triggers the built-in link setup code: https://github.com/systemd/systemd/blob/09541e49ebd17b41482e447dd8194942f39788c0/rules/80-net-setup-link.rules The udev rule is triggering on action add (=> probe on driver level). At least on the device I tested, it seems that there is no event on open... Any other ideas what could be used as trigger to configure the link? -- Stefan
