- *              This module implements the AX.25 protocol for kernel-based
- *              devices like TTYs. It interfaces between a raw TTY, and the
- *              kernel's AX.25 protocol layers, just like slip.c.
- *              AX.25 needs to be separated from slip.c while slip.c is no

- *              This method clears the way to implement other kiss protocols
