I assumed this was rhashtable-related and so sending to Thomas and
Herbert, but if not please let me know and I get it to the right person.
I'm happy to test any patches you may have to resolve this. Also, let me
know if you need my config file to reproduce.
Thanks

Thanks for the report.
This should be fixed by the patches posted in the thread:

Applying those fixed my problem. I also just pulled the latest net-next
with this series applied and that works as well.
