Subject: [RFCv5 PATCH net-next 03/20] net: replace general features macroes with global netdev_features variables
There are many netdev_features bits group used in kernel. The definition
will be illegal when using feature bit more than 64. Replace these macroes
with global netdev_features variables, initialize them when netdev module
init.
