From b6474465e962369c1cd4b00324c2e175e2cf30cf Mon Sep 17 00:00:00 2001 From: James Smart Date: Tue, 12 Apr 2022 15:19:47 -0700 Subject: [PATCH] scsi: lpfc: Requeue SCSI I/O to upper layer when fw reports link down During heavy I/O stress tests with 100+ vports and cable pulls, it may take a while before the vport logs back into the fabric to resume I/O. Currently, the driver immediately fails the I/O with DID_ERROR. Change behavior to return DID_REQUEUE, and rely on SCSI layer's max retry of 5 before erroring out the I/O.
