This commit introduced the auto-validation function which allows users to compare the batch of packets obtained from different action implementations against the linear action implementation. The autovalidator function can be triggered at runtime using the following command: $ ovs-appctl odp-execute/action-impl-set autovalidator Signed-off-by: Emma Finn <emma.finn@intel.com> Acked-by: Harry van Haaren <harry.van.haaren@intel.com> Acked-by: Sunil Pai G <sunil.pai.g@intel.com> Acked-by: Eelco Chaudron <echaudro@redhat.com> Signed-off-by: Ian Stokes <ian.stokes@intel.com>
