Subject: [isci-rnc PATCH v1 27/37] isci: Add protocol indicator for TMF requests.
Date: Thu, 22 Mar 2012 17:30:18 -0700 [thread overview]
Message-ID: <20120323003018.18065.23809.stgit@dwillia2-linux.jf.intel.com> (raw)
In-Reply-To: <20120323002504.18065.45709.stgit@dwillia2-linux.jf.intel.com>
From: Jeff Skirvin <jeffrey.d.skirvin@intel.com>
Requests contructed as task management requests need to have the protocol
indicator set so the completion decode can observe any RNC suspension
conditions.
