Kenneth D. Merry d3c7b9a08a MFp4 (//depot/projects/mps/...)
Bring in a driver for the LSI Logic MPT2 6Gb SAS controllers.

This driver supports basic I/O, and works with SAS and SATA drives and
expanders.

Basic error recovery works (i.e. timeouts and aborts) as well.

Integrated RAID isn't supported yet, and there are some known bugs.

So this isn't ready for production use, but is certainly ready for
testing and additional development.  For the moment, new commits to this
driver should go into the FreeBSD Perforce repository first
(//depot/projects/mps/...) and then get merged into -current once
they've been vetted.

This has only been added to the amd64 GENERIC, since that is the only
architecture I have tested this driver with.
