Merge branch 'nfp-add-flow-steering-support'

Louis Peens says:

====================
nfp: add flow-steering support

This short series adds flow steering support for the nfp driver.
The first patch adds the part to communicate with ethtool but
stubs out the HW offload parts. The second patch implements the
HW communication and offloads flow steering.

After this series the user can now use 'ethtool -N/-n' to configure
and display rx classification rules.
