      Given OVS and OVN workloads using hashmaps for flow tables, MAC learning, or connection tracking,

      When the hashmap implementation is switched to 7-node-bucket style,

      Then hashmap iteration and lookup operations show measurable performance improvement with no functional regression in existing tests.

      ( ) The epics work is available in a downstream build (nightly/async or other)

      ( ) Test coverage is available in downstream CI if applicable

      ( ) All cards under the epic have been moved to Done

      ( ) Failed Test Plans have bugs added as children to the epic/feature.

      This epic tracks all the effort needed to deliver the solution related to the feature request described below.

      What's the feature?

      Switching the OVS+OVN hashmap to a 7-node-bucket style. 

      Why is it needed?

      The OVS+OVN hashmap is used all over both codebases and improving its iteration and search efficiency would speed up OVS and OVN.

      Who will benefit? 

      All OVS + OVN users.
