Subject: [RFCv7 PATCH net-next 05/36] net: atlantic: replace const features initialization with NETDEV_FEATURE_SET
The atlantic driver use netdev_features in global structure
initialization. Changed the its netdev_features_t memeber
to netdev_features_t *, and make it refer to a netdev_features_t
global variables.
