+Subject: [PATCH 066/146] DSS2: Swap field offset values w/ VRFB rotation
+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf-8
+Content-Transfer-Encoding: 8bit
+
+The field 0 and field 1 offset values were still incorrect when VRFB
+rotation is used. Swap them to put the fields into proper order.
