Multicast routing is today handled in the input path. Locally generated MC
packets don't hit the IPMR code. Thus if a VXLAN remote address is
multicast, the driver needs to set an OIF during route lookup. In practice
that means that MC routing configuration needs to be kept in sync with the
VXLAN FDB and MDB. Ideally, the VXLAN packets would be routed by the MC
routing code instead.

I think this leads to kmemleaks:

hit by netdevsim udp_tunnel_nic.sh

Thanks, I'll take a look.

Also, do you have a branch with the iproute2 patches we could pull 
in the CI?

My bad, didn't think of it:
