Merge branch 'flow_keys_digest'
Tom Herbert says:
====================
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.).
Version 2:
- Add keyval parameter to __flow_hash_from_keys which allows caller to
set the initval for jhash
- Perturb always does flow dissection and creates hash based on
input perturb value which acts as the keyval to __flow_hash_from_keys
- Added a _flow_keys_digest_data which is used in make_flow_keys_digest.
This fills out the digest by populating individual fields instead
of copying the whole structure.
