I would assume that OVS-ODP does not set up any classification rules so all packets go to some default destination anyway (some pktio input queue). Can't the ODP implementation then bypass the classification stage if it can understand (and it should be able to) that classification does not change the behavior? I would rather not invent explicit configurations when the implementation should be able to deduce the best behavior based on the configuration provided by the user. > Any opinions about these options? > > Regards, > > Zoli > _______________________________________________ > lng-odp mailing list > lng-odp@lists.linaro.org > https://lists.linaro.org/mailman/listinfo/lng-odp >
