[PATCH 5.16 196/203] scsi: lpfc: Remove NVMe support if kernel has NVME_FC disabled

From: Greg Kroah-Hartman
Date: Mon Feb 14 2022 - 05:42:35 EST


From: James Smart <jsmart2021@xxxxxxxxx>

commit c80b27cfd93ba9f5161383f798414609e84729f3 upstream.

The driver is initiating NVMe PRLIs to determine device NVMe support. This
should not be occurring if CONFIG_NVME_FC support is disabled.

Correct this by changing the default value for FC4 support. Currently it
defaults to FCP and NVMe. With change, when NVME_FC support is not enabled
in the kernel, the default value is just FCP.
