Subject[PATCH 3.18 181/185] scsi: lpfc: Fix issue_lip if link is disabled
Date
3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: James Smart <jsmart2021@gmail.com>

[ Upstream commit 2289e9598dde9705400559ca2606fb8c145c34f0 ]

The driver ignored checks on whether the link should be kept
administratively down after a link bounce. Correct the checks.
