I'm trying to setup an app that needs the tun device

I can run the command
mknod /dev/net/tun c 10 200

whithout any problem but the driver is not loaded. No mentiion of its load in kern.log (I added the package rsyslog to get the logs...)

and the command
tunctl -t tap0 -u pi

Failed to open '/dev/net/tun' : No such device

I could not find either any file named tun.ko on the system.....

Using latest kernel : 4.11.2
