Subject: [PATCH net-next 0/7] net: Eliminate calls to flow_dissector and introduce flow_keys_digest

In this patch set we add skb_get_hash_perturb which gets the skbuff
hash for a packet and perturbs it using a provided key and jhash1.
This function is used in serveral qdiscs and eliminates many calls
to flow_dissector and jhash3 to get a perturbed hash for a packet.

To handle the sch_choke issue (passes flow_keys in skbuff cb) we
add flow_keys_digest which is a digest of a flow constructed
from a flow_keys structure.

This is the second version of these patches I posted a while ago,
and is prerequisite work to increasing the size of the flow_keys
structure and hashing over it (full IPv6 address, flow label, VLAN ID,
etc.).

Tom Herbert (7):
  net: Add skb_get_hash_perturb
  sched: Eliminate use of flow_keys in sch_fq_codel
  sched: Eliminate use of flow_keys in sch_hhf
  sched: Eliminate use of flow_keys in sch_sfb
  sched: Eliminate use of flow_keys in sch_sfq
  net: Add flow_keys digest
  sch_choke: Use flow_keys_digest
