If anyone has any objections, please let me know. ------------------ From: Shahar Shitrit [ Upstream commit 3f8e82a020a5c22f9b791f4ac499b8e18007fbda ] Since the documentation for mlx5_toggle_port_link states that it should only be used after setting the port register, we add a check for the return value from mlx5_port_set_eth_ptys to ensure the register was successfully set before calling it.
