Maintainers are capable of merging whatever they want to merge. However, I
wouldn't make hasty choices. The changes I've been submitting have been deployed
on millions of router instances and are more feature rich.

I believe I worked with you on this change, or something like it,

https://lkml.org/lkml/2019/3/19/970

I don't think Christophe has even addressed this. I've converted many
architectures, and Cisco uses my changes on at least 4 different
architecture. With products deployed and tested.

I will resubmit my changes as soon as I can.
