Support bit on kernel module

i wrote my own kernel module but while doing modprobe , i am getting error “unsupported module”.
–allow_unsupported option allow loading the module.
how can i set support = external in my module ?

If you want a tainted kernel, you should configure /etc/modprobe.d/10-unsupported-modules.conf to allow loading of unsupported kernel modules.

Please read:

and the warnings in /etc/modprobe.d/10-unsupported-modules.conf
