Hi, There is no KNI or TUN/TAP port implemented in librte_port currently, hence please consider contributing this to DPDK. If the throughput of this device is not the first priority for you, I would actually recommend the TUN/TAP approach rather than KNI, as KNI seem to require significant maintenance due to constant changes in kernel header files, while TUN/TAP is very stable. KNI and TUN/TAP could also be leveraged straight away by librte_port as rte_ethdev type of port if they would be made available as PMDs. I know there were some plans to make this happen, but for some reason looks like the plans did not become reality. Thanks, Cristian
