From ebc99feba7378349e2bfae7018af062767382f6c Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Tue, 4 Jan 2011 11:54:26 +0200 Subject: [PATCH] Bluetooth: Add flag to track managment controlled adapters This patch adds a HCI_MGMT flag to track adapters which are under the control of the management interface. This is needed to make sure that new kernels will work with old user space versions. I.e. behaviour which could break old user space versions (but is needed by the management interface) should not be exhibited when the HCI_MGMT flag is not set.
