90 * SPARC PLATFORM REMARKS:
91 * IOCTL data structures that contain pointers
92 * will have different sizes in the driver and applications
93 * (as the app. will not use 8-byte pointers).
94 * Apps should use MPTFWDOWNLOAD and MPTCOMMAND.
95 * The driver will convert data from
96 * mpt_fw_xfer32 (mpt_ioctl_command32) to mpt_fw_xfer (mpt_ioctl_command)
97 * internally.
99 * If data structures change size, must handle as in IOCGETINFO.
