This patch set is the V1 implementation to combine the CD and DFC design. Both patches intend to refactor datapath to avoid costly sequential subtable search.
CD and DFC patch sets: CD: [PATCH v2 0/5] dpif-netdev: Cuckoo-Distributor implementation https://mail.openvswitch.org/pipermail/ovs-dev/2017-October/340305.html DFC: [PATCH] dpif-netdev: Refactor datapath flow cache https://mail.openvswitch.org/pipermail/ovs-dev/2017-November/341066.html The first commit is a rebase of Jan Scheurich's patch of [PATCH] dpif-netdev: Refactor datapath flow cache The second commit is to incorporate CD's way-associative design into DFC to improve the hit rate. The third commit is to change the distributor to cache an index of flow_table entry to improve memory efficiency. RFC of this patch set: https://mail.openvswitch.org/pipermail/ovs-dev/2018-January/343411.html RFC->V1: 1. rebase to master head. 2. The last commit is totally rewritten to use the flow_table as indirect table. The CD/DFC distributor will cache the index of flow_table entry. 3. Incorporate commit 2 into commit 1. (Bhanu's comment) 4. Change DFC to be always on in commit 1.
