+ * This header file is used by the iSeries virtual I/O device
+ * drivers.  It defines the interfaces to the common functions
+ * (implemented in drivers/char/viopath.h) as well as defining
+ * common functions and structures.  Currently (at the time I
+ * wrote this comment) the iSeries virtual I/O device drivers
+ * that use this are
+ *   drivers/block/viodasd.c
+ *   drivers/char/viocons.c
+ *   drivers/char/viotape.c
+ *   drivers/cdrom/viocd.c
+ *
+ * The iSeries virtual ethernet support (veth.c) uses a whole
+ * different set of functions.
