Merge branch 'net-dsa-bcm_sf2-CFP-support'
Florian Fainelli says:
====================
net: dsa: bcm_sf2: CFP support
This patch series adds support for the Broadcom Compact Field Processor (CFP)
which is a classification and matching engine built into most Broadcom switches.
We support that using ethtool::rxnfc because it allows all known uses cases from
the users I support to work, and more importantly, it allows the selection of a
target rule index, which is later used by e.g: offloading hardware, this is an
essential feature that I could not find being supported with cls_* for instance.
Thanks!
Changes in v3:
- rebased against latest net-next/master after Vivien's changes
Changes in v2:
- fixed modular builds reported by kbuild test robot
