 This is a known issue; mptutil(8) isn't endian-clean (actually the IOCTL-
 interface of mpt(4) is little-endian even on big-endian architectures
 and actually also should stay that way as otherwise we would need to add
 code to the driver to convert all possible configuration pages, which
 doesn't make sense), which requires a non-trivial amount of work to fix.
 That mptutil(8) is working that much in it's current state actually is
 really amazing. For now you're probably better off using the software
 RAID equivalent.
