Segfault on port operation

You should declare the driver_int function using this macro:
The function tun_init() is redundant for a dynamically linked driver.
It is called after the driver is loaded (i.e. after driver_init()).
There are of course many functions missing from your driver entry.
Notably you have no function for sending data to the port. :)
