Subject: [dpdk-dev] [PATCH v1 5/8] net/mlx5: remove umem field dependency on dv
Date: Wed,  3 Jun 2020 15:05:59 +0000
Message-ID: <20200603150602.4686-6-ophirmu@mellanox.com> (raw)
In-Reply-To: <20200603150602.4686-1-ophirmu@mellanox.com>

umem field is used in several structs. Its type 'struct mlx5dv_devx_umem
*' is changed to 'void *'. This change will allow non-Linux OS
compilations.
