+Subject: [PATCH 43/57] net-next: mediatek: enable special tag indication for
+ PDMA
+
+The Ingress special tag indication was only enabled for QDMA and not PDMA.
+Properly initialize the STAG bit. This broke HW NAT and Qos from working
+for traffic coming in via a DSA device. The PPE failed to properly parse
+the traffic as it was not expecting the special tag.
