Not obvious why this patch set never got merged. Most likely because
it required upstream FreeBSD libraries that were not merged at the time.

Is this still of interest?

Has the support for RDMA and IB been merged in upstream FreeBSD?


Does the meson build handle the case where the required dependencies are
not present in the version of FreeBSD being used?

If nothing else, the driver needs to be resubmitted to address 3 years
of changes to mlx5 common code. And will need an entry in MAINTAINERS.
