[ovs-dev] [PATCH 0/2] datapath flow key hashing performance optimization

[Andrew Evans]

Jesse noticed that the datapath doesn't need to hash the entire struct
sw_flow_key, just the parts relevant to that flow. This patch series reorders
struct sw_flow_key to put the optional/variable parts of the flow key last, and
hashes only the portion actually used to describe the flow.

Andrew Evans (2):
  datapath: Rearrange struct sw_flow_key to put IPv4/IPv6-specific
    details last.
  datapath: Hash only the part of struct sw_flow_key populated by
    flow_extract().
