Bug#892794: systemd-networkd fails to configure IPv6 without MTU from RA

[Norbert]

Hi Ciryl,

I tested your systemd-build from
  https://people.debian.org/~kibi/systemd/

The problem is resolved with your patched version. :-)


I urge the package maintainers to introduce this new build really fast
into stretch. I could imagine, this affects a whole bunch of people:

My ISP hands out unmanageable cable router/modems to it's customers.
These devices do not provide a default MTU in their RAs.
Therefore I have no chance of handling such a scenario other than
patching systemd-networkd.

So thanks for getting things right!
