Subject: [PATCH net-next v07 4/9] hinic3: Add .ndo_set_features and .ndo_fix_features
Implement following callback function:
.ndo_set_features
.ndo_fix_features
The .ndo_set_features function includes five features: rx_csum,
tso, lro, rx_cvlan and vlan_filter.
Add these new features in netdev_feature_init.
