From d23264a896a931c4b355c102d8e9d46649195ba4 Mon Sep 17 00:00:00 2001 From: Andre Guedes Date: Fri, 25 Nov 2011 20:53:38 -0300 Subject: Bluetooth: Add dev_flags to struct hci_dev This patch adds the dev_flags field to struct hci_dev. This new flags variable should be used to define flags related to BR/EDR and/or LE controller itself. It should be used to define flags which represents states from the controller. The dev_flags is cleared in case the controller sends a Reset Command Complete Event to the host. Also, this patch adds the HCI_LE_SCAN flag which was created to track if the controller is performing LE scan or not. The flag is set/cleared when the controller starts/stops scanning. This is an initial effort to stop using hdev->flags to define internal flags since it is exported to userspace by an ioctl.
