/* The auerswald ISDN devices have a logical channel concept. Many channels are
 * realized via one control endpoint or INT endpoint. At the receiver side, these
 * messages must be dispatched. Some data may be for an application which is
 * connected through the char interface, other data may be D-channel information
 * routed to ISDN4LINUX. The auerscon struct is used to dispatch the data.
