LSI1064 and LSI1064E and mpt

[Johannes.Kruger at nokia.com]

The problems are:
(1) It's not a RAID-0 Vol but a RAID-1 (The PCI-X card reports it
correctly, but not the PCI-Express. This should not differ.
(2) The RAID volume is very slow (both cards are slow with RAID volume -
this is the problem I am trying to track down), approx 4.5 Mbyte/sec
instead of 30 Mbyte/sec I get when no RAID volume is configured. With
the RAID volume, even just 1 disk in the volume get slow performance.
(3) With the PCI-X card the config page has info in it, so I can add
code to print the resync complete percentage on intervals I choose.
(4) I added some code to print out the volume config page 0 info on the
PCI-Express card:
The header looks ok, but not the config page in the same structure, it's
all zeroes.
