Currently, all available structure fields in gsmmux.h except those
for gsm_config are commented.

Fix this by adding appropriate comments to the not commented fields.
Note that 'mru' and 'mtu' refer to the size without basic/advanced option
mode header and byte stuffing as defined in the standard in chapter 5.7.2.

v1 -> v2:
Added remark regarding the mru/mtu size comment as this was unclear in the
review.

Maybe you can start documenting them using kernel-doc? And convert the 
others and expose them all to Documentation and finally to:
https://www.kernel.org/doc/html/latest/
?
