+FreeBSD Prerequisites
+---------------------
+
+Currently there is an ongoing review of FreeBSD OFED drivers and RDMA-core libraries.
+Their status can be tracked at
+`OFED Review <https://reviews.freebsd.org/p/vag.singh_oneconvergence.com/>`__.
+
+The FreeBSD MLX5 PMD requires these OFED changes to run.
+To build successfully, file ``/usr/include/infiniband/mlx5dv.h`` should be present. It
+is generally missing on FreeBSD.
