From 1d9bf13a9cf91f8faf221e98a64dd1157bcf5fa9 Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Wed, 30 May 2007 12:57:11 -0500 Subject: [SCSI] iscsi class: add iscsi host set param event The iscsi class uses the set_param event to set session and connection params. This patch adds a set_host_param so we can set host level values.
