DESCRIPTION
       The  modldrv  structure is used by device drivers to export driver spe‐
       cific information to the kernel.

STRUCTURE MEMBERS

	 char		   *drv_linkinfo;
	 struct dev_ops	   *drv_dev_ops;

       drv_modops	Must  always  be  initialized  to   the	  address   of
			mod_driverops.	This member identifies the module as a
			loadable driver.

       drv_linkinfo	Can be	any  string  up	 to  MODMAXNAMELEN  characters
			(including  the	 terminating  NULL  character), and is
			used to describe the module and	 its  version  number.
			This is usually the name of the driver and module ver‐
			sion information, but can contain other information as
			well.
