Can't get 6in4 tunnel working

Installing and Using OpenWrt
1

Although kmod-sit is installed now without any issue, dmesg | grep sit returns empty. I suppose this is the reason I can't get 6in4 tunnel working. How could I fix it?
Thanks.

I removed kmod-sit and 6-in4, then added them again. Still lsmod | grep sit does not return anything.

root@OpenWrt:/etc/config# opkg list-installed | grep 6in4
6in4 - 26
root@OpenWrt:/etc/config# opkg list-installed | grep kmod-sit
kmod-sit - 5.4.94-1

modprobe sit

Nothing returned after modprobe. I even searched in /proc/modules for sit but it is not loaded. I found this:
