Overview
========
This document describes the format of data used for communicating with
the kernel using a so-called Bluetooth Management sockets. These sockets

HCI_CHANNEL_CONTROL (3) when creating a raw HCI socket. In C the needed
code would look something like the following:
are available starting with Linux kernel version 3.4
The following kernel versions introduced new commands to the Bluetooth
Management API:
Linux kernel v3.4 Version 1.0
Linux kernel v3.5 Version 1.1
Linux kernel v3.7 Version 1.2
Linux kernel v3.9 Version 1.3
Linux kernel v3.13 Version 1.4
