From 94af1220985c71cd80d6c161b7a42c51ef08b923 Mon Sep 17 00:00:00 2001 From: Sarah Sharp Date: Fri, 2 Apr 2010 15:34:10 -0700 Subject: [PATCH] USB: Add stream ID field to struct urb. Bulk endpoint streams were added in the USB 3.0 specification. Streams allow a device driver to overload a bulk endpoint so that multiple transfers can be queued at once. Add a new field, stream_id, to struct urb so that USB 3.0 drivers can specify which stream they want the URB to be queued to.
