[test case] configure interface e.g. Name=ens3 [Network] DHCP=ipv4 LinkLocalAddressing=ipv6 [Link] MTUBytes=1550 start/restart networkd, the interface will never reach 'routable' stage and will not get an IPv4 address. [regression potential] any regressions would likely occur during networkd configuration/startup/restart, and would likely cause failure to successfully setup the interface. [other info] this is a regression-proposed caused by incomplete backport for bug 1850704 To manage notifications about this bug go to: https://bugs.launchpad.net/systemd/+bug/1852754/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
