Bug 261674

The mpsutil (and mprutil) tool states these commands in its usage message:

Commands include:

version                                 version


While all show/flash subcommands are described in the manpage, the 'debug dumpregs' and 'slot set status' commands aren't.
'debug dumpregs' doesn't take arguments and is quite self-explanatory, but the 'slot set status' command needs arguments of which only the enclosure handle and slot number could be extracted e.g. from an 'mpsutil show devices' listing. However, the 'status' (which needs to be a numerical argument) can't be guessed from any output of mpsutil/mprutil and isn't mentioned in any of the mpr/mprutil/mps/mpusutil manpages.
