From b2c6416736b847b91950bd43cc5153e11a1f83ee Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Wed, 30 May 2007 12:57:16 -0500 Subject: [SCSI] iscsi class, iscsi_tcp, ib_iser: add sysfs chap file The attached patches add sysfs files for the chap settings to the iscsi transport class, iscsi_tcp and ib_iser. This is needed for software iscsi because there are times when iscsid can die and it will need to reread the values it was using. And it is needed by qla4xxx for basic management opertaions. This patch does not hook in qla4xxx yet, because I am not sure the mbx command to use.
