The HCI monitor channel can be used to monitor all packets and events
from the Bluetooth subsystem. The monitor is not bound to any specific
HCI device and allows even capturing multiple devices at the same time.

to represent each key.
Some notes: authenticated is used to identify that the key may be used
to setup a HIGH security link. As the same list is used to store both
the STK's and the LTK's the type field is used so we can separate
between those two types of keys and if the key should be used when
in the master or slave role.

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.
