From 6a8a0d3621745279a131d95f0204dc9ddac60d55 Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Wed, 28 Jun 2006 12:00:31 -0500 Subject: [SCSI] iscsi: pass target nr to session creation So the drivers do not use the channel numbers, but some do use the target numbers. We were just adding some goofy variable that just increases for the target nr. This is useless for software iscsi because it is always zero. And for qla4xxx the target nr is actually the index of the target/session in its FW or FLASH tables. We needed to expose this to userspace so apps could access those numbers so this patch just adds the target nr to the iscsi session creation functions. This way when qla4xxx's Hw thinks a session is at target nr 4 in its hw, it is exposed as that number in sysfs.
