Subject: [PATCH net-next 0/6] net: sched: indirect tc block cb registration

John says:

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.

RFC v2 -> PATCH
 - removed embedded tracking function from indir block register (now up to
   driver to clean up after itself)
 - refactored NFP code due to recent submissions
 - removed priv list clean function in NFP (list should be cleared by
   indirect block unregisters)

RFC v1->v2:
 - free allocated owner struct in block_owner_clean function
 - add geneve type helper function
 - move test stub in NFP (v1 patch 2) to full tunnel offload
   implementation via indirect blocks (v2 patches 3-8)

John Hurley (6):

  nfp: flower: increase scope of netdev checking functions
  nfp: flower: offload tunnel decap rules via indirect TC blocks
  nfp: flower: remove TC egdev offloads
  nfp: flower: remove unnecessary code in flow lookup
