2017-07-17	xdp: sample program for new bpf_redirect helper	John Fastabend	1	-0/+102
	This implements a sample program for testing bpf_redirect. It reports the number of packets redirected per second and as input takes the ifindex of the device to run the xdp program on and the ifindex of the interface to redirect packets to.
