From 6281bfe0002acd7765cb4afe0304c36962ad6b15 Mon Sep 17 00:00:00 2001 From: "James.Smart@Emulex.Com" Date: Mon, 28 Nov 2005 11:41:33 -0500 Subject: [PATCH] [SCSI] lpfc 8.1.1 : Fixes for short cable pulls Cause: Link bounces were causing discovery ELS's to be killed. Driver was not properly flushing ELS commands upon the subsequent link bounces. Thus, processing of ELS post link bounce erroneously assumed discovery failure and device loss.
