> Subject: [PATCH v2 1/2] common/mlx5: add glue function for domain sync
>
> In rdma-core, the "mlx5dv_dr_domain_sync" function was already
> provided. It is used to flush the rule submission queue. The wrapper
> function in the glue layer is added for using this.
> It only supports DR flows right now the same as domain creating and
> destroying functions.
