Hi,

I confirm a decent performance improvement with DPDK and balance-tcp bonding:

lb-output-action=false

rx: 740 Mbps 1446 kpps

lb-output-action=true

rx: 860 Mbps 1680 kpps

I'm running a very simple test with a tweaked version of testpmd which
generates 256 L4 flows, I guess that with much flows the improvement
is way higher.
