I have ported the RPL module code from 3.17 to 4.9 kernel. and i had installed tool from bellow site. https://github.com/joaopedrotaveira/rpl-userspace-tools when i was trying to enable RPL with bellow command. kernel and Raspberry pi is getting hang and after few seconds all processes are going to crash. againg to start, it is taking restart(power off/on). # enable RPL router $ sudo rpl-ctl enable eth0 please help me.. to activate RPL in 4.9 kernel.
