- - ipv4ll with multiple interfaces doesn't work when both dhcp and
- ipv4ll is used. for some reasons the kernel will currently pick an
- ipv4ll source address to reach non-ipv4ll gateways.
- - dhcp and ipv4ll should probably be skipped for "lo" devices, even
- if the user has a catchall .network file installed, that might
- theoretically match it.
