Hi All, Currently RoCE is always enabled by default in mlx5 and there is no option for the user to disable it. This change introduces new generic devlink param "enable_roce". User should set desired param value and reload the driver to get desired configuration. Two options for reload: 1) reload mlx5_ib driver. 2) reload via devlink, once the devlink mlx5 reload support [1] lands in net-next branch, after this series is applied. mlx5 devlink reload is not part of this patchset since it depends on changes from net-next tree. RoCE will still be enabled by default after this change. In case of no objection this series will be applied to mlx5-next branch and sent later as pull request to both rdma-next and net-next branches.
