NAME
    sata_tran_reset_dport - reset SATA port or SATA device 


SYNOPSIS
    #include <sys/sata/sata_hba.h>

    int sata_tran_reset_dport(dev_into_t *dev_info, sata_device_t *sata_device);

INTERFACE LEVEL
    Consolidation Private

PARAMETERS
    dev_info		Pointer to a dev_info_t structure, referring to
    			the HBA device instance.
      sata_device       Pointer to sata_device structure identifying the target
      			port or SATA device or the whole controller

DESCRIPTION
    sata_tran_reset_dport() function is called by the SATA HBA framework during
    error recovery. It should perform HBA-specific sequence of resetting
    the port or a device or the whole controller, as specified by the 
    sata_address in sata_device argument. Reset operation should be followed 
    internally by SATA HBA driver with an operation of re-establishing 
    communication with an attached device. 
    SATA HBA driver should return a port status in the appropriate fields of
    the sata_device structure passed as the argument to the function. 
    This function shall not be called from the interrupt context.

RETURN VALUE
    sata_tran_reset_dport must return:
    
    SATA_SUCCESS	Port or device was successfully reset. The function
    			should return SATA_SUCCESS even when there is no device
    			attached or the communication with the device cannot be
    			established, as long as the device port state is known.
    
    SATA_FAILURE	The status of the port could not be determined after
    			the reset operation.
