where do I find the n_gsm module

Hi there,

this is probably a stupid question ..
but where do I fin the N_gsm module.

I want to install a utility (https://github.com/Rtone/cmux)
that needs the N_gsm module loaded.
However neither on raspian nor ubuntu this module is available.

thanks
robert

In your kernel source tree do:
find . | grep n_gsm
