net: Add netif_is_vxlan()
Add the ability to determine whether a netdev is a VxLAN netdev by calling the above mentioned function that checks the netdev's rtnl_link_ops. This will allow modules to identify netdev events involving a VxLAN netdev and act accordingly. For example, drivers capable of VxLAN offload will need to configure the underlying device when a VxLAN netdev is being enslaved to an offloaded bridge. Convert nfp to use the newly introduced helper.
