[PATCH 1/9] Bluetooth: Add BT_AMP_POLICY socket option

[Mat Martineau <mathewm@codeaurora.org>]

Allow control of AMP functionality on L2CAP sockets. By default,
connections will be restricted to BR/EDR.  Manipulating the
BT_AMP_POLICY option allows for channels to be moved to or created
on AMP controllers.
