Fix identifying 2308 cards
Add support for more than 8 MSI-X interrupts.
Tidy up interrupt assignement and card ID messages.
Added code to support using MSI-X interrupts across multiple
reply queues. Not tested with anything other than 3008 yet.
Use MSI-X interrupts, just one for now.
Pre-allocate array for request sense buffers, similar to command frames.
No more messing about with scsi_alloc_consistent_buf().
Initial modifications using the code changes present between
the LSI source code for FreeBSD drivers. Specifically the changes
between from mpslsi-source-17.00.00.00 -> mpslsi-source-03.00.00.00.
This mainly involves using a different scatter/gather element in
frame setup.
Changes to enable driver to compile.
Header paths, object lists, etc.
