From caf3827a65af476c71eaeb79636869a4ab128d48 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Fri, 19 May 2006 16:44:55 -0400 Subject: [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.
