====================
nfp: introduce flower offload capabilities

this series adds flower offload to the NFP driver. It builds on recent
work to add representor and a skeleton flower app - now the app does what
its name says.

In general the approach taken is to allow some flows within
the universe of possible flower matches and tc actions to be offloaded.
It is planned that this support will grow over time but the support
offered by this patch-set seems to be a reasonable starting point.

Key Changes since v2:
* Revised flow structures to simplify setup/teardown and locking of stats
* Addressed other code-change review of v2

Other review questions regarding v2 have been answered on netdev.
