ALWAYS_GUARD_BAND_SCH_Q bit in TAS config register is descripted as this: 0: Guard band is implemented for nonschedule queues to schedule queues transition. 1: Guard band is implemented for any queue to schedule queue transition. The driver set guard band be implemented for any queue to schedule queue transition before, which will make each GCL time slot reserve a guard band time that can pass the max SDU frame. Because guard band time could not be set in tc-taprio now, it will use about 12000ns to pass 1500B max SDU. This limits each GCL time interval to be more than 12000ns. This patch change the guard band to be only implemented for nonschedule queues to schedule queues transition, so that there is no need to reserve guard band on each GCL. Users can manually add guard band time for each schedule queues in their configuration if they want.
