IEEE 802.15.4 and Bluetooth networking stacks share 6lowpan compression code. Instead of introducing Makefile/Kconfig hacks, build this code as a separate module referenced from both ieee802154 and bluetooth modules. This fixes the following build error observed in some kernel configurations: net/built-in.o: In function `header_create': 6lowpan.c:(.text+0x166149): undefined reference to `lowpan_header_compress' net/built-in.o: In function `bt_6lowpan_recv': (.text+0x166b3c): undefined reference to `lowpan_process_data' Reported-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Dmitry Eremin-Solenikov <dmitry_eremin@mentor.com> Signed-off-by: David S.

IEEE Std 802.15.4 defines a low data rate, low power and low
|
|
complexity short range wireless personal area networks. It was
|
|
designed to organise networks of sensors, switches, etc automation
|
|
devices. Maximum allowed data rate is 250 kb/s and typical personal
|
|
operating space around 10m.

Say Y here to compile LR-WPAN support into the kernel or say M to

compile it as modules.
