Author: mav Date: Wed Nov 26 12:25:00 2014 New Revision: 275112 URL: https://svnweb.freebsd.org/changeset/base/275112 Log: Make isp_find_pdb_by_*() search for targets in portdb in reverse order. Records with target_mode == 1 are allocated from the end of portdb, so it seems logical to start search from the end not traverse whole array.
