1 review trailer.
From: Eli Cohen <redacted> Add code to accept MAC configuration through vdpa tool. The MAC is written into the config struct and later can be retrieved through get_config(). Examples: 1. Configure MAC: $ vdpa dev config set vdpa0 mac 00:11:22:33:44:55 2. Show configured params: $ vdpa dev config show vdpa0: mac 00:11:22:33:44:55 link down link_announce false mtu 0 speed 0 duplex 0 Signed-off-by: Eli Cohen <redacted> Reviewed-by: Parav Pandit <redacted> --- drivers/vdpa/mlx5/net/mlx5_vnet.c | 17 +++++++++++++++++ 1 file changed, 17 insertions(+)
