[PATCH] UHCI: store the period in the queue header
This patch (as689) stores the period for periodic transfers (interrupt and ISO) in the queue header. This is necessary for proper bandwidth tracking (not yet implemented). It also makes the scheduling of ISO transfers a bit more rigorous, with checks for out-of-bounds frame numbers.
