Author: mav Date: Mon Nov 30 21:55:35 2015 New Revision: 291528 URL: https://svnweb.freebsd.org/changeset/base/291528 Log: MFC r291188: Rip off target mode support for parallel SCSI QLogic adapters. Hacks to enable target mode there complicated code, while didn't really work. And for outdated hardware fixing it is not really interesting. Initiator mode tested with Qlogic 1080 adapter is still working fine.
