This is SCST driver for ISP Qlogic chipsets commonly used in many SCSI and FC host bus adapters. Supported chipset are listed in README file, incomplete list of supported HBA's is in doc/Hardware.txt . It is based on Matthew Jacob's multiplatform driver for ISP chipsets, which can be download from ftp://ftp.feral.com/pub/isp/isp_dist.tgz git-svn-id: http://svn.code.sf.net/p/scst/svn/trunk@135 d57e44dd-8a1f-0410-8b47-8ef2f437770f
