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

    [root@kerneldev010.prn1 ~/pktgen]# ./pktgen_sample03_burst_single_flow.sh -i eth0 -s 64 -d fe80::f652:14ff:fec2:a14c -m f4:52:14:c2:a1:4c -b 32 -6

    [root@kerneldev011.prn1 ~]# tcpdump -i eth0 -nn -c3 port 9
    tcpdump: WARNING: eth0: no IPv4 address assigned

    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
