[dpdk-dev] Recommended LNS-compatible host interface?

DPDK supports a number of different interface types. Given this, at this time what is the favoured (virtual) interface type for host-only applications where Linux network stack compatibility is required? Previously we used KNI (we found this to be "unreliable" when not bound to a real ethdev). Is this still the best option?


PS: The reliability issues we saw were related to ARP. Manually adding an ARP entry caused the entire board to lock up (i.e. hard reboot necessary). At the time, we got around this by not using ARP as we didn't really need it. However, this likely won't be possible going into the future.
