Specifically this uses a 'big hammer' feature bit
to do the offload or not. If the bit is set you get offloaded rules
if it is not then rules will not be offloaded. If we can agree on
this patch series there are some more patches on my queue we can
talk about to make the offload decision per rule using flags similar
to how we do l2 mac updates. Additionally the error strategy can
be improved to be hard aborting, log and continue, etc. I think
these are nice to have improvements but shouldn't block this series.

John,

I thought we've got into agreement in netdev that the offloading
directive would be a tri-state creature (sw, hw and fail the op if
can't, hw and fallback to sw). Can you please elaborate what do you
mean by "make the offload decision per rule using flags similar to how
we do l2 mac updates"

I think John's changes are an intermediate step in a long term
evoluation.

I'm going to apply John's changes as-is, and people can submit relative
changes on top if they want.
