Hi. I test the 4.9 kernel and i have missed multicast protocol:

root@vero:~# grep CONFIG_IP_MROUTE /boot/config-4.9.113-29-osmc 
# CONFIG_IP_MROUTE is not set

root@vero:~# grep CONFIG_IP_MROUTE /boot/config-3.14.29-160-osmc 
CONFIG_IP_MROUTE=y
# CONFIG_IP_MROUTE_MULTIPLE_TABLES is not set

I need it

thanks in advance
