The current version of the library relies on a recent enough version of the module/headers as it's fairly new stuff. It's interacting with the driver at a fairly low level. I assume it's similar for the Infiniband equivalents, but I don't know what the Mellanox ones require. I don't know the details of what support is required, or if there's useful out-of-tree support for different versions, but OPA is probably most commonly used on RHEL 7-ish kernels.
