[dpdk-dev] KNI performance is not what is claimed

[Stephen Hemminger]

I wonder if KNI is claiming performance that was never measured on current CPU, OS, DPDK.

With single stream and TCP testing on IXGBE (DPDK), I see lowest performance with KNI.

		Rx		Tx
	KNI	3.2 Gbit/sec	1.3 Gbit/sec
	TAP	4.9		4.7
	Virtio	5.6		8.6

Perhaps for 18.11 we should change documentation to remove language claiming
better performance with KNI, and then plan for future deprecation?
