The features handling has been reworked in net-next and patches like this
won't apply as the code you're patching has changed. Also core code now
does a lot of the related work and you'll need to tell it what to do with
any new flags.
What properties does a device or driver need to meet to set this flag? It
seems to be set a bit too unconditionally. For example, does it work if one
disables scatter/gather?
