Subject: [PATCH net 0/2] gre: Fix default IPv6 multicast route creation.

When fixing IPv6 link-local address generation on GRE devices with
commit 3e6a0243ff00 ("gre: Fix again IPv6 link-local address
generation."), I accidentally broke the default IPv6 multicast route
creation on these GRE devices.

Fix that in patch 1, making the GRE specific code yet a bit closer to
the generic code used by most other network interface types.

Then extend the selftest in patch 2 to cover this case.

Guillaume Nault (2):
  gre: Fix IPv6 multicast route creation.
  selftests: Add IPv6 multicast route generation tests for GRE devices.
