Not sure what other RDMA driver you are talking about but as for Cornelis
Networks, we do have a packaged up version of our software. However it is meant
to make things easier on end users to bridge the gap between the distro kernel
drivers and the upstream kernel.
It's definitely not a requirement and plenty of folks do use distro
kernels/drivers. I'm not sure how many large sites are using something straight
off kernel.org but the upstream hfi1 driver is 100% the real deal.
We continually develop on and test the upstream kernel. Our goal is always to
upstream patches first. We learned that lesson the hard way when we first tried
to upstream hfi1.
