pktgen: add sample script pktgen_sample01_simple.sh
Add the first basic pktgen samples script pktgen_sample01_simple.sh, which demonstrates the a simple use of the helper functions. Removing pktgen.conf-1-1 as that example should be covered now. The naming scheme pktgen_sampleNN, where NN is a number, should encourage reading the samples in a specific order. Script cause pktgen sending with a single thread and single interface, and introduce flow variation via random UDP source port. Usage example and help: ./pktgen_sample01_simple.sh -i eth4 -m 00:1B:21:3C:9D:F8 -d 192.168.8.2 Usage: ./pktgen_sample01_simple.sh [-vx] -i ethX -i : ($DEV) output interface/device (required) -s : ($PKT_SIZE) packet size -d : ($DEST_IP) destination IP -m : ($DST_MAC) destination MAC-addr -c : ($SKB_CLONE) SKB clones send before alloc new SKB -v : ($VERBOSE) verbose -x : ($DEBUG) debug Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: David S.
