BNEP protocol support
CONFIG_BLUEZ_BNEP
BNEP (Bluetooth Network Encapsulation Protocol) is Ethernet
emulation layer on top of Bluetooth. BNEP is required for Bluetooth
PAN (Personal Area Network).
To use BNEP, you will need user-space utilities provided in the
BlueZ-PAN package.
For more information, see <http://bluez.sourceforge.net>.
Say Y here to compile BNEP support into the kernel or say M to
