Subject: [PATCH v5 34/34] cxlflash: Fix to escalate to LINK_RESET on login timeout
Date: Thu,  1 Oct 2015 10:58:52 -0500	[thread overview]
Message-ID: <1443715132-26119-1-git-send-email-mrochs@linux.vnet.ibm.com> (raw)
In-Reply-To: <1443714773-9176-1-git-send-email-mrochs@linux.vnet.ibm.com>

From: Manoj Kumar <manoj@linux.vnet.ibm.com>

A 'login timed out' asynchronous error interrupt is generated if no
response is seen to a FLOGI within 2 seconds.  If the time out error
is not escalated to a LINK_RESET the port will not be available for
use. This fix provides the required escalation.
