      Given a DPDK physical port (e.g., ens4f0) in an OVS-DPDK user-mode bridge,

      When the system administrator sets dpdk-lsc-interrupt=false in the NetworkManager connection profile,

      Then, the OVS interface’s dpdk-lsc-interrupt option is set to false and the LSC detection uses polling mode instead of interrupts.

      Definition of Done

      • NetworkManager’s OVS plugin supports mtu_request configuration.
      • Integration tests validate polling mode and MTU propagation.
      • Code is part of a downstream build attached to an errata and backported to RHEL 9.4.
      • Documentation updated for new OVS-DPDK options.

      We need to enable NetworkManager’s OVS plugin to configure dpdk-lsc-interrupt=false and propagate mtu_request to DPDK physical ports in a bond.

      These settings are important for RHOSP NFV/telco customers using OVS-DPDK with polling mode drivers to achieve maximum performance.

      This ticket is related to RHEL-53956.
