Subject: [PATCH 19/42] lpfc: Fix sg_seg_cnt for HBAs that don't support NVME
Date: Wed, 14 Aug 2019 16:56:49 -0700	[thread overview]
Message-ID: <20190814235712.4487-20-jsmart2021@gmail.com> (raw)
In-Reply-To: <20190814235712.4487-1-jsmart2021@gmail.com>

On an SLi-3 adapter which does not support NVMe, but with the
driver global attribute to enable nvme on any adapter if it
does support NVMe (e.g. module parameter lpfc_enable_fc4_type=3),
the SGL and total SGE values are being munged by the protocol
enablement when it shouldn't be.

Correct by changing the location of where the NVME sgl information
is being applied, which will avoid any SLI-3-based adapter.
