The rdma-core and kernel drivers are being submitted. The expected version supporting MANA is with rdma-core v42 and Linux 5.19 (or 5.20).

I'm not sure if there is a way to enforce meson to build on a certain rdma-core or kernel version. Is it okay to add the following information to doc/guides/nics/mana.rst for specifying the version requirement?


Current RDMA core package and Linux kernel
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

- Minimal Linux kernel version: 5.19.
- Minimal RDMA core version: v42 (see `RDMA core installation documentation`_).
