Bluetooth: Add support for limited privacy mode
Introduce a limited privacy mode indicated by value 0x02 to the mgmt Set Privacy command. With value 0x02 the kernel will use privacy mode with a resolvable private address. In case the controller is bondable and discoverable the identity address will be used. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
