Subject: [RFCv6 PATCH net-next 18/19] net: use netdev_xxx_features helpers
Replace the direct using for features members of netdev
with netdev_xxx_features helpers, for the nic drivers are
not supposed to modify netdev_features directly.
I'mo not sure for this patch is necessary, just keep the
same rule with others.
