Subject: [RFC PATCH 0/4] switch device: offload policy attributes

From: Roopa Prabhu <>

This series aims at introducing new policy attibutes/flags to enable
selective offloading of kernel network objects.
This is in the context of supporting switch devices in the linux kernel.

    - All kernel network objects (routes, neighs, bridges, bonds, vxlans)
      can be offloaded (This is true today with a few exceptions maybe)

policy points:
    - By default all objects exist in software (kernel)
    - Per object flag to add/del/show in kernel, hardware or both
    - System global option to turn on/off offloads for all network objects.
      This is for systems who want to turn offloading on for all network objects
      by default. us :). Apps dont need to know about offloading in this
      model. (TBD)

Patches are based on jiri/sfeldma's rocker work.

Apologize for the incomplete and untested code. This is a sample patch
 to get some initial feedback.

Roopa Prabhu (4):
  rtnetlink: new flag NLM_F_HW_OFFLOAD to indicate kernel object
    offload to hardware
  netdev: new feature flag NETIF_F_HW_OFFLOAD to indicate netdev object
    offload to hardware
  swdevice: new generic op to set bridge port attr
  bridge: make hw offload conditional on bridge and bridge port offload
