I believe Paolo is planning to look next week. No idea why the patch
got marked as Accepted 🤷️

I don't think it's a political discussion. Or at least not in the sense 
of hidden agendas because our agendas aren't hidden. I'm a maintainer
of an open source networking stack, you're working for a vendor who
wants to sell their own networking stack.

Perhaps you'd like to believe, and importantly have your customers
believe that it's the same networking stack. It is not, the crucial,
transport part of your stack is completely closed.

I don't think we can expect Linus to take a hard stand on this, but
do not expect us to lend you our APIs and help you sell your product.

Saying that RDMA/RoCE is not proprietary because there is a "standard"
is like saying that Windows is an open source operating system because
it supports POSIX.

My objectives for netdev are:
 - give users vendor independence
 - give developers the ability to innovate

I have not seen an RDMA implementation which could deliver on either.
Merging this code is contrary to my objectives for the project.

I already said it. If you wanted to configure IPsec for RoCE you should
have added an API in the RDMA subsystem.
