Subject[PATCH AUTOSEL for 4.9 28/52] scsi: lpfc: Fix crash during Hardware error recovery on SLI3 adapters
Date
From: James Smart <jsmart2021@gmail.com>

[ Upstream commit 5d181531bc6169e19a02a27d202cf0e982db9d0e ]

if REG_VPI fails, the driver was incorrectly issuing INIT_VFI
(a SLI4 command) on a SLI3 adapter.
