89  * @interval: Interval for periodic endpoints, in frames or microframes.
92  * @periodic: Set if this is a periodic ep, such as Interrupt
102  * @fifo_size: The size of the FIFO (for periodic IN endpoints)
104  * @fifo_load: The amount of data loaded into the FIFO (periodic IN)
106  * @size_loaded: The last loaded size for DxEPTSIZE for periodic IN
115  * For periodic IN endpoints, we have fifo_size and fifo_load to try
116  * and keep track of the amount of data in the periodic FIFO for each
119  * as in shared-fifo mode periodic in acts like a single-frame packet

903  * @non_periodic_sched_inactive: Inactive QHs in the non-periodic schedule.
