Commit 975508879 "Bluetooth: make bluetooth 6lowpan as an option"
ensures that 6LOWPAN_IPHC is turned on when we have BT_6LOWPAN
enabled in Kconfig, but it allows building the IPHC code as
a loadable module even if the entire Bluetooth stack is built-in,
and that causes a link error.
We can solve that by moving the 'select' statement into CONFIG_BT,
which is a "tristate" option to enforce that 6LOWPAN_IPHC can
only be a module if BT also is a module.

Bluetooth is low-cost, low-power, short-range wireless technology.
|
|
It was designed as a replacement for cables and other short-range
|
|
technologies like IrDA. Bluetooth operates in personal area range
|
|
that typically extends up to 10 meters. More information about
|
|
Bluetooth can be found at <http://www.bluetooth.com/>.
|
|
|
|
Linux Bluetooth subsystem consist of several layers:
|
|
Bluetooth Core
|
|
HCI device and connection manager, scheduler
|
|
SCO audio links
|
|
L2CAP (Logical Link Control and Adaptation Protocol)
|
|
SMP (Security Manager Protocol) on LE (Low Energy) links
|
|
HCI Device drivers (Interface to the hardware)
|
|
RFCOMM Module (RFCOMM Protocol)
|
|
BNEP Module (Bluetooth Network Encapsulation Protocol)
|
|
CMTP Module (CAPI Message Transport Protocol)
|
|
HIDP Module (Human Interface Device Protocol)
|
|
|
|
Say Y here to compile Bluetooth support into the kernel or say M to
|
|
compile it as module (bluetooth).
|
|
|
|
To use Linux Bluetooth subsystem, you will need several user-space
|
|
utilities like hciconfig and bluetoothd. These utilities and updates
|
|
to Bluetooth kernel modules are provided in the BlueZ packages. For
|
|
more information, see <http://www.bluez.org/>.
