Controlling DPDK interfaces with KNI is known to be broken. Kni calls
usepspace with network mutex held. The problem is not fixable.
The kernel does provide netlink and devlink API's but there is no generic
solution with DPDK.

Last time I tried.
Virtio user was as fast as KNI and consumed less cpu. Was seeing 10mpps
Tap was much slower. Like 1mpps.
Vpp uses virtio user.

Hi,
As discussed today in the techboard meeting, KNI has probably
better alternatives today without using an out-of-tree module.
Virtio-user is a good candidate to replace KNI.
What is the performance of TAP?
Is there a way to leverage af_packet, af_xdp, or even pcap interfaces?
