| Subject: scsi: lpfc: Fix issue_lip if link is disabled |
| |
| 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. |
