+ * 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.  */

+ * In general, you send a command down to the interface and receive

+ * and responses, the driver will take care of figuring out which

+ * (IPMI_UNUSED_ADDR_TYPE).  When talking to an IPMB channel, you must

+ * When talking to normal channels, the driver takes care of the
+ * details of formatting and sending messages on that channel.  You do
+ * not, for instance, have to format a send command, you just send
+ * whatever command you want to the channel, the driver will create
