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
