From f6cc2a774aa7f5469f381b52804bb244d4f8f4d7 Mon Sep 17 00:00:00 2001 From: Kevin Barnett Date: Thu, 11 Mar 2021 14:15:39 -0600 Subject: [PATCH] scsi: smartpqi: Add support for BMIC sense feature cmd and feature bits Determine support for supported features from BMIC sense feature command instead of config table. Enable features such as: RAID 1/5/6 write support, SATA wwid, and encryption.
