- *
- * Currently supported:
- *	* raw IP-in-HDLC
- *	* Cisco HDLC
- *	* Frame Relay with ANSI or CCITT LMI (both user and network side)
- *	* PPP
- *	* X.25
- *
- * Use sethdlc utility to set line parameters, protocol and PVCs
- *
- * How does it work:
- * - proto.open(), close(), start(), stop() calls are serialized.
- *   The order is: open, [ start, stop ... ] close ...
- * - proto.start() and stop() are called with spin_lock_irq held.
