Subject: [PATCH RFC net-next 6/7] netdev_features: convert NETIF_F_VLAN_CHALLENGED to IFF_VLAN_CHALLENGED
Inability to handle VLAN-tagged packets is more of an attribute, not
a feature.
Convert it to a private flag and add it to IFF_ONE_FOR_ALL with special
handling in netdev_increment_priv_flags() as it previously was in
netdev_increment_features().
Note that starting from this change, ETHTOOL_A_FEATURES_NOCHANGE
will always return 0 to userspace as there's no more
NETIF_F_NEVER_CHANGE.
