      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.

      ( ) Code changes are included in a downstream build attached to an errata.

      ( ) All required testing (manual and/or automated) passes successfully.

      ( ) Related documentation updates (if applicable) have been completed.

      We need to enable NetworkManager’s OVS plugin to configure dpdk-lsc-interrupt=false. 

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