For the operation function pointer, it is set_speed. >>>> >>>> where lane indicates the lane of the PHY and speed is the PHY speed in hertz. >>> >>> Does lane here means the number of lanes?

Each lane is suppose to be independent of each other. -Loc -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
