Can you provide a brief or whitepaper discussing this complexity
please? This pushback is news to me, Mellanox and the RDMA ecosystem
has been doing this for over 15 years now. I would need something

However, I believe we can get an exception approval for single license
MIT or BSD-3-Clause for this code.
