Subject: [dpdk-dev] [PATCH v1 4/8] net/mlx5: split mlx5 ethdev under Linux directory
Date: Wed, 10 Jun 2020 09:32:29 +0000
Message-ID: <20200610093233.23902-5-ophirmu@mellanox.com> (raw)
In-Reply-To: <20200610093233.23902-1-ophirmu@mellanox.com>

File mlx5_ethdev.c is partially moved to linux/mlx5_ethdev_os.c for
functions which are Linux specific. Functions which are Linux agnostics
remain in mlx5_ethdev.c file.
