would be good to capture the GRE use case that found the bug and the
MPLS version as test cases under tools/testing/selftests/net. Both
should be doable using namespaces.  

I believe Vadim is working on MPLS side, how does this look for GRE?

I like the template you followed. :-)

:)

The test case looks good to me, thanks for doing it.

Noob question, why do we need that 2 sec wait with IPv6 sometimes?
I've seen it randomly in my local testing as well I wasn't sure if 
it's a bug or expected.

I make a v6 tunnel on top of a VLAN and for 2 secs after creation 
I get the wrong route in ip -6 r g.
