pktgen: add sample script pktgen_sample03_burst_single_flow.sh
Add the pktgen samples script pktgen_sample03_burst_single_flow.sh
that demonstrates how to acheive maximum performance.
If correctly tuned[1] single CPU 10Gbit/s wirespeed small pkts is
possible[2] which is 14.88Mpps. The trick is to take advantage of the
"burst" feature introduced in commit 38b2cf2982 ("net: pktgen:
packet bursting via skb->xmit_more").
