We have encountered an issue where IPv6 cannot be enabled on interfaces besides eth0 when using Docker.
This limitation is problematic for configurations that require IPv6 support on multiple interfaces.
It appears that the value set for net.ipv6.conf.default.X is not working anymore, as new interfaces are created.
To fix it, we need to configure a proper driver_opt when interfaces are connected to devices.

We are working on a fix that will be released as soon as possible.
Sorry for the inconvenient
