+Subject: [PATCH] net: ethernet: mtk_eth_soc: ppe: add support for multiple
+ PPEs
+
+Add the missing pieces to allow multiple PPEs units, one for each GMAC.
+mtk_gdm_config has been modified to work on targted mac ID,
+the inner loop moved outside of the function to allow unrelated
+operations like setting the MAC's PPE index.
+Introduce a sanity check in flow_offload_replace to account for
+non-MTK ingress devices.
+Additional field 'ppe_idx' was added to struct mtk_mac in order
+to keep track on the assigned PPE unit.
