      Given a system administrator has a DPDK interface configured with Nmstate,

      When they attempt to apply an updated configuration to the DPDK interface using Nmstate,

      Then, the configuration should apply successfully without any misleading error messages and
      no "InvalidArgument: Invalid property: missing field devargs" error should appear if the changes are successfully applied.

      Definition of Done:

      • The implementation meets the acceptance criteria
      • Integration tests are written and pass
      • The code is part of a downstream build attached to an errata

      What were you trying to do that didn't work?

      Change attributes of ovs dpdk interface got

      NmstateError: InvalidArgument: Invalid propriety: missing field `devargs`

      but all the changes actually applied successfully.

      What is the impact of this issue to you?

      Please provide the package NVR for which the bug is seen:
