--- Comment #18 from ChloƩ Desoutter ---
Actually further MicroSemi driver analysis lets me think that the proper,
recommended value is 256.
$ egrep '#define\s+MAX_[IO]B_QUEUE_ELEMENTS' *.h
pm8001_sas.h:#define MAX_IB_QUEUE_ELEMENTS 256
pm8001_sas.h:#define MAX_OB_QUEUE_ELEMENTS 256
so I shall test with this value for PM8001_MPI_QUEUE and see if I achieve real
stability with constant workloads.
