NAME
       scsi_get_device_type_string - look up per-device-type, returning matching information string

SYNOPSIS
       #include <sys/scsi/scsi.h>

       char *scsi_get_device_type_string(char *prop_name,
		 dev_info_t  *dip, struct scsi_device  *devp);

INTERFACE LEVEL
       Solaris DDI specific (Solaris DDI).

PARAMETERS
       prop_name    Name of string array property that contains a list of paired device-type information.

       dip	    Pointer to the device info node for this HBA driver.

       devp	    Pointer to a scsi_device(9S) structure of the target.

DESCRIPTION
       The  scsi_get_device_type_string()  function  looks up the prop_name property, which can be specified in the HBA's driver.conf(4)file. This
       property allows specification of per-device-type information. The syntax for prop_name in a driver.conf(4) file is:

       The formal syntax is:

	 prop_name = <duplet> [, <duplet> *];

       where:

	 <duplet> := "<vid+pid>", "<information"

       The string <vid+pid> is returned by the device on a SCSI inquiry command. This string can contain any character	in  the  range	0x20-0x7e.
       Characters  such as double quote (") or single quote ('), which are not permitted in property value strings, are represented by their octal
       equivalent (for example, 42 and 47). Trailing spaces can be truncated.

       For example:

	 scsi_vhci_failover_override =
		  "STK	   FLEXLINE 400",   "f_asym_lsi",
		  "SUN	   T4",        "f_tpgs";;

       The scsi_get_device_type_string()  function  searches  the  list  of  duplets  for  a  matching	INQUIRY  string.  If  a  match	is  found,
       scsi_get_device_type_string  returns  a copy of the <information> string. The meaning of the returned <information> string is determined by
       the caller.

RETURN VALUES
       scsi_get_device_type_string() returns a copy of the matching <information> string, or if no match is found, NULL is returned. When  a  non-
       NULL value is returned, the caller is responsible for freeing the <information> string via:

	 kmem_free(info, strlen(info) + 1);

CONTEXT
       This function can be called from kernel or interrupt context.
