From 36dfe324fd4b5efd9ef1a5b4c352bbb158952e24 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 24 Oct 2012 18:14:07 +0200 Subject: usb: Add USB_RET_ADD_TO_QUEUE packet result code This can be used by usb-device code which wishes to process an entire endpoint queue at once, to do this the usb-device code returns USB_RET_ADD_TO_QUEUE from its handle_data class method and defines a flush_ep_queue class method to call when the hcd is done queuing up packets.
