After adding the case "ARPHRD_6LOWPAN" to generate IPv6 address for BT interface in IPv6 module (addrconf.c file); kernel gets panicked. May be this panic is because I am using below setup. 1. Linux kernel version 3.10. 2. For 6LoWPAN: Just copied [net/6lowpan/.. and net/Bluetooth/.. code from 4.0.2 kernel] Rest all other modules are older only (kernel 3.10) including IPV6 module. As I cannot upgrade whole kernel due to official reasons, please suggest which other dependent modules I need to upgrade mandatorily to get the 6LoWPAN working for Bluetooth properly. Or Above setup is sufficient to work for Bluetooth 6lowpan? Please let me know your suggestions.
