From 57127f157298ea2dacbbc878a3c5d2a5daca772c Mon Sep 17 00:00:00 2001 From: James Smart Date: Sat, 27 Oct 2007 13:37:05 -0400 Subject: [PATCH] [SCSI] lpfc 8.2.3 : Added support for ASICs that report temperature Added support for ASICs that report temperature. Temperature notices are reported as events and logged. Temperature can be read via sysfs.
