Subject: [RFC net-next v2 0/8] indirect tc block cb registration

This patchset introduces an alternative to egdev offload by allowing a
driver to register for block updates when an external device (e.g. tunnel
netdev) is bound to a TC block. Drivers can track new netdevs or register
to existing ones to receive information on such events. Based on this,
they may register for block offload rules using already existing
functions.

The patchset also implements this new indirect block registration in the
NFP driver to allow the offloading of tunnel rules. The use of egdev
offload (which is currently only used for tunnel offload) is subsequently
removed.

John Hurley (8):
  net: sched: register callbacks for indirect tc block binds
  net: add netif_is_geneve()
  nfp: flower: include geneve as supported offload tunnel type
  nfp: flower: allow non repr netdev offload
  nfp: flower: add infastructure for indirect TC block register
  nfp: flower: offload tunnel decap rules via indirect TC blocks
  nfp: flower: remove TC egdev offloads
  nfp: flower: remove unnecessary code in flow lookup
