[PATCH 13/20] lpfc: Rework lpfc Kconfig for NVME options
jsmart2021 at gmail.com

Sat Mar 4 09:30:33 PST 2017
From: James Smart <jsmart2021 at gmail.com>
Reworked Kconfig so that lfpc only requires the scsi stack.
NVME Initiator and NVME Target support can be enabled if
the other NVMe subsystems have been enabled.
