	Add a '-6' option to the sample pktgen scripts for sending out IPv6 packets.

2015-05-22	pktgen: add benchmark script pktgen_bench_xmit_mode_netif_receive.sh	Jesper Dangaard Brouer	1	-0/+86
	This script pktgen_bench_xmit_mode_netif_receive.sh is a benchmark script, which can be used for benchmarking part of the network stack. This can be used for performance improving or catching regression in that area. The script is developed for benchmarking ingress qdisc path, original idea by Alexei Starovoitov. This script don't really need any hardware. This is achieved via the recently introduced stack inject feature "xmit_mode netif_receive". See commit 62f64aed622b6 ("pktgen: introduce xmit_mode '<start_xmit\|netif_receive>'"). Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
