I've updated the MPT fusion target driver for LSI SCSI/FC/SAS HBAs. The original SCST MPT driver was based on the 1.00.13 LSI sample target driver. LSI has since released version 1.00.14 of the sample target driver. I've ported all the changes from .13 to .14 into the SCST MPT driver for consistency. I've also updated the SCST MPT driver to compile under 2.6.24 and 2.6.25.4. Finally, I force the SCSI parallel transfer rate to very slow depending on the SCSI HBA firmware revision. Newer versions of SCSI HBA firmware have a bug where the incorrect amount of data is transferred for non-divisible-by-4 length transfers (like standard 14 byte REQUEST SENSE). LSI is aware of the problem and I'll update the driver to restore functionality upon a new good SCSI HBA firmware release. I still have not confirmed operation with LSI SAS or FC HBAs.

This is the SCST development repository. It contains not a single project SCST as one can think, but a number of them, which are divided as the following: 1. SCST core in scst/ subdirectory 2. Target drivers in own subdirectories qla2x00t/, iscsi-scst/, etc. 3. User space programs in usr/ subdirectory, like fileio_tgt. 4. Some various docs in doc/ subdirectory. Those subprojects are in most cases independent from each other, although some of them depend from the SCST core. They put in the single repository only to simplify their development, they are released independently. Thus, use "make all" only if you really need to build everything. Otherwise build only what you need, like for iSCSI-SCST: make scst scst_install iscsi iscsi_install For more information about each subproject see their README files.
