Subject: [PATCH v2 09/21] lpfc: Fix FCP hba_wqidx assignment
Date: Fri, 29 Sep 2017 17:34:35 -0700	[thread overview]
Message-ID: <20170930003447.10747-10-jsmart2021@gmail.com> (raw)
In-Reply-To: <20170930003447.10747-1-jsmart2021@gmail.com>

From: Dick Kennedy <dick.kennedy@broadcom.com>

The driver is encountering  oops in lpfc_sli_calc_ring.

The driver is setting hba_wqidx for FCP based on the
policy in use for NVME. The two may not be the same.
Change to set the wqidx based on the FCP policy.
