pktgen: add sample script pktgen_sample02_multiqueue.sh
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.
