NAME
    sata_address - structure specifying SATA address
    
SYNOPSIS
    #include <sys/sata/sata_hba.h> 

INTERFACE LEVEL
    Consolidation Private

DESCRIPTION
    SATA device address structure containing addressing components of a sata
    port or device.  The sata port may be a sata controller's device port or
    a Port Multiplier's device port or a Port Multiplier's host port. The sata
    device may be a device attached to one of the controller or the port
    Multiplier device ports. The qual field indicates how the address should
    be interpreted.

STRUCTURE MEMBERS

    uint_8	cport	/* SATA controller's device port number*/
    uint_8 	pmport  /* Port Multiplier port number */
    uint_8  	qual	/* Address qualifier flag */

    cport  	SATA controller's device port number.

    pmport	Port Multiplier's device port number. Valid only when
    		the address qualifier is set to SATA_ADDR_PMPORT or
    		SATA_ADDR_DPMPORT.

    qual	Address qualifier flag, used to specify what is being addressed:
    
            	SATA_ADDR_DCPORT 	Address specifies SATA device attached
            				directly to a controller's port
            				
            	SATA_ADDR_DPMPORT 	Address specifies SATA device attached
            				to a Port Multiplier's device port
            				
            	SATA_ADDR_CPORT 	Address specifies controller's device
            				port itself, not an attached device
            				
            	SATA_ADDR_PMPORT 	Address specifies Port Multiplier
            				itself, not the attached device
            				
		SATA_ADDR_CNTRL  	Address refers to the whole controller

                SATA_ADDR_PMULT         Address specifies Port Multiplier
					attached to a controller's device port.
