This involves significant changes to the mps(4) driver, but is not a complete rewrite. Some of the changes in this version of the driver: - Integrated RAID (IR) support. - Support for WarpDrive controllers. - Support for SCSI protection information (EEDP). - Support for TLR (Transport Level Retries), needed for tape drives. - Improved error recovery code. - ioctl interface compatible with LSI utilities. mps.4: Update the mps(4) driver man page somewhat for the driver changes. The list of supported hardware still needs to be updated to reflect the full list of supported cards. conf/files: Add the new driver files. mps/mpi/*: Updated version of the MPI header files, with a BSD style copyright. mps/*: See above for a description of the new driver features. modules/mps/Makefile: Add the new mps(4) driver files.
