-Subject: [PATCH] ethernet: mediatek: mtk_eth_soc: add support for
- initializing the PPE
-
-The PPE (packet processing engine) is used to offload NAT/routed or even
-bridged flows. This patch brings up the PPE and uses it to get a packet
-hash. It also contains some functionality that will be used to bring up
-flow offloading later
