NAME
    sata_tran_ioctl - SATA HBA-specific IOCTLs handler
    
SYNOPSIS
    #include <sys/sata/impl/sata_hba.h>

    int    sata_tran_ioctl(dev_info_t *dev_info, int cmd, intptr_t arg);

INTERFACE LEVEL
    Consolidation Private

PARAMETERS
    dev_info 	Pointer to a dev_info_t structure, referring to
    		the HBA device instance.
    			
    cmd   	Argument specifying IOCTL operation
    
    arg		Pointer to operation-specific data

DESCRIPTION
    sata_tran_ioctl() is a SATA HBA function performing HBA-specific IOCTLs
    operations.  The arg points to IOCTL argument containing HBA's
    operation-specific information. SATA HBA Framework will pass to SATA HBA
    driver sata_tran_ioctl() function all IOCTL requests that cannot be handled
    by SATA HBA Framework itself not by nexus ioctl handler.  The 'mode',
    'cred_p' and 'rval_p' arguments of ioctl(9E) call are dropped and device
    number ('dev') argument of an ioctl(9E) is converted to dev_info. 
    'cmd' and 'arg' arguments are passed without change to sata_tran_ioctl().


RETURN VALUE
    sata_tran_ioctl() returns SATA_SUCCESS on success or SATA_FAILURE on
    failure.  In a case of a failure, the errno has to be set up to indicate
    a type of error.  If a specified operation is not supported SATA HBA
    driver, errno shall be set to ENOSUP.
