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.

|
* 04-30-07 02.00.00 Corresponds to Fusion-MPT MPI Specification Rev A.
|
|
* 08-31-07 02.00.01 Added Command Buffer Data Location Address Space bits to
|
|
* BufferPostFlags field of CommandBufferPostBase Request.
|
|
* 02-29-08 02.00.02 Modified various names to make them 32-character unique.
|
|
* 10-02-08 02.00.03 Removed NextCmdBufferOffset from
|
|
* MPI2_TARGET_CMD_BUF_POST_BASE_REQUEST.
|
|
* Target Status Send Request only takes a single SGE for
|
|
* response data.
