From 7e21addcd0ad87696c17409399e56e874931da57 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Wed, 18 Nov 2009 01:05:00 +0100 Subject: [PATCH] Bluetooth: Return ENETDOWN when interface is down Sending commands to a down interface results in a timeout while clearly it should just return ENETDOWN. When using the ioctls this works fine, but not when using the HCI sockets sendmsg interface.
