From d1889a08964568253594710bfb188171ab0c5d0c Mon Sep 17 00:00:00 2001 From: Ronnie Sahlberg <ronniesahlberg@xxxxxxxxx> Date: Fri, 26 Feb 2010 13:16:50 +1100 Subject: [PATCH] Based on Or Gerlitz patch from http://lists.wpkg.org/pipermail/stgt/2009-September/003207.html Add support to tgtd and tgtadm to specify which command port to use for the management channel. This allows running multiple instances of tgtd on teh same host, each using a unique command channel.
