Subject: [PATCH 2/2] scsi: hisi_sas: Change frame type for SET MAX commands
Date: Thu, 28 Dec 2017 18:20:47 +0800 [thread overview]
Message-ID: <1514456447-213928-3-git-send-email-chenxiang66@hisilicon.com> (raw)
In-Reply-To: <1514456447-213928-1-git-send-email-chenxiang66@hisilicon.com>
According to ATA protocol, SET MAX commands belong to different frame types.
So judge features field of SET MAX commands to decide which frame type they
belongs to.
