/*

 * This file describes an interface to an IPMI driver.  You have to

 * have a fairly good understanding of IPMI to use this, so go read

 * the specs first before actually trying to do anything.

 *

 * With that said, this driver provides a multi-user interface to the

 * IPMI driver, and it allows multiple IPMI physical interfaces below

 * the driver.  The physical interfaces bind as a lower layer on the

 * driver.  They appear as interfaces to the application using this

 * interface.

 *

 * Multi-user means that multiple applications may use the driver,

 * send commands, receive responses, etc.  The driver keeps track of

 * commands the user sends and tracks the responses.  The responses

 * will go back to the application that send the command.  If the

 * response doesn't come back in time, the driver will return a

 * timeout error response to the application.  Asynchronous events

 * from the BMC event queue will go to all users bound to the driver.

 * The incoming event queue in the BMC will automatically be flushed

 * if it becomes full and it is queried once a second to see if

 * anything is in it.  Incoming commands to the driver will get

 * delivered as commands.

 *

 * This driver provides two main interfaces: one for in-kernel

 * applications and another for userland applications.  The

 * capabilities are basically the same for both interface, although

 * the interfaces are somewhat different.  The stuff in the

 * #ifdef KERNEL below is the in-kernel interface.  The userland

 * interface is defined later in the file.  */
