The only change between 9.4.1-5 and 9.4.1-6 indeed is IPv6-related: * Merge patch from upstream Git: Use netlink to workout address flags. This patch was taken straight from upstream Git and will be included in the upcoming 9.4.2 release. If that change has any adverse effect, I suggest opening a bug upstream (https://github.com/NetworkConfiguration/dhcpcd/issues) and linking this Debian bug to it. > After trying other things, I manually added a /64 (rather than /128) > link-local address to the PPPoE interface.
