Subject: [RFCv8 PATCH net-next 07/55] net: ethernet: mtk_eth_soc: replace const features initialization with NETDEV_FEATURE_SET
The mediatek driver use netdev features in global structure
initialization. Changed the netdev_features_t memeber to
netdev_features_t *, and make it refer to a global constant
netdev_features_t variable.
