Subject: [patch net-next v4 RFC 00/15] introduce programable flow dissector and cls_flower

Per Davem's request, I prepared this patchset which introduces programmable
flow dissector. For current users of flow_keys, there is a wrapper
skb_flow_dissect_flow_keys which maintains the previous behaviour.
For purposes of cls_flower, couple of new dissection keys were introduced.

Note that this dissector can be also eventually used by openvswitch code.

Also, I plan to get rid of *skb_flow_get_ports(export) and *__skb_get_poff as
their functionality can be now implemented by skb_flow_dissect as well.

Ideas, comments?

Jiri Pirko (15):
  net: change name of flow_dissector header to match the .c file name
  flow_dissector: remove unused function flow_get_hlen declaration
  net: move *skb_get_poff declarations into correct header
  flow_dissector: fix doc for __skb_get_hash and remove couple of empty
    lines
  net: move __skb_get_hash function declaration to flow_dissector.h
  net: move __skb_tx_hash to skbuff.c
  net: move netdev_pick_tx and dependencies to net/core/dev.c
  flow_dissector: fix doc for skb_get_poff
  flow_dissector: introduce programable flow_dissector
  flow_dissect: use programable dissector in skb_flow_dissect and
    friends
  flow_dissector: add missing header includes
  flow_dissector: introduce support for ipv6 addressses
  flow_dissector: introduce support for Ethernet addresses
  flow_dissector: change port array into src,dst tuple
  tc: introduce Flower classifier
