I forgot to note this series needs to be merged after the series here,

 https://patchwork.ozlabs.org/project/netdev/list/?series=174562

Otherwise we may hit the error from that series in selftests. It should
be no problem to let the series sit on the list for a few days while
the above series gets into bpf-next but if you would prefer I can resubmit
later.

Thanks,
John
