You are stumbling upon my next objective here. This patch set does not
support this because it wasn't clear how to do it. The plan was to get
the base driver merged first then introduce a way to specify an offload
channel.
If you must know, I introduced a rxnfc flow_spec ring cookie to specify
an offload filter. Not sure if this is the right way to do it or not,
but figured this would be a future discussion.
