    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 pktgen samples script pktgen_sample02_multiqueue.sh that
    demonstrates generating packets on multiqueue NICs.

    Specifically notice the options "-t" that specifies how many
    kernel threads to activate. Also notice the flag QUEUE_MAP_CPU,
    which cause the SKB TX queue to be mapped to the CPU running the
    kernel thread. For best scalability people are also encourage to
    map NIC IRQ /proc/irq/*/smp_affinity to CPU number.

    Usage example with "-t" 4 threads and help:
    ./pktgen_sample02_multiqueue.sh -i eth4 -m 00:1B:21:3C:9D:F8 -t 4

    Usage: ./pktgen_sample02_multiqueue.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
    -t : ($THREADS) threads to start
    -c : ($SKB_CLONE) SKB clones send before alloc new SKB
    -b : ($BURST) HW level bursting of SKBs
    -v : ($VERBOSE) verbose
    -x : ($DEBUG) debug

    Removing pktgen.conf-2-1 and pktgen.conf-2-2 as these examples
    should be covered now.
