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.
