Hi,

on my host I turned on MFI_DEBUG and enabled MFI_D_MISC, and
below is is what it spewed on bootup.  You'll note "max commands"
is at 1008, and even though it's divided by the number of logical
drives, there ought to be enough for good parallellism.

Our driver is from OpenBSD mfi.c 1.66 according to the leftover
RCS Id, while their "head" is at 1.137.  Their revision 1.129
with

   give every target on the bus max_cmds openings. iopools means
   they will properly share access to them.

and 1.114 with

   cut mfi over to using iopools.

   this gets rid of NO_CCB, provides better scheduling of io
   between busy logical volumes on the same controller, and makes
   the ioctl and sensor paths more reliable.

among the commit messages where a corresponding change does not
appear to have been made to our sources.  This sounds like rather
largish changes, and it's not a given how this fits into the
NetBSD framework, so they may not be easy to apply.  And it's not
certain that it's these changes which are the important ones...

Regards,

- Håvard
