+Subject: [PATCH] soc: fsl: dpio: Enable ACP port in Linux QMAN driver
+
+Setting the software portal configuration DE(dequeue stashing
+enable) bit. This should enable the ACP (Accelerator Coherency
+Port).
+
+During test this improved performance on the LS2088a slightly. No
+effect on the LX2160a.
