trafgen --dev eth0 --conf trafgen.cfg
              This is the most simple and, probably, the most common use
              of trafgen. It will generate traffic defined in the
              configuration file ''trafgen.cfg'' and transmit this via
              the ''eth0'' networking device. All online CPUs are used.

       trafgen --dev eth0 --conf trafgen.cfg --cpus 2-4
              Instead of using all online CPUs, transmit traffic from
              CPUs 2, 3, and 4.

       trafgen -e | trafgen -i - -o lo --cpp -n 1
              This is an example where we send one packet of the built-
              in example through the loopback device. The example
              configuration is passed via stdin and also through the C
              preprocessor before trafgen's packet compiler will see it.

       trafgen --dev eth0 --conf fuzzing.cfg --smoke-test 10.0.0.1
              Read the ''fuzzing.cfg'' packet configuration file (which
              contains drnd() calls) and send out the generated packets
              to the ''eth0'' device. After each sent packet, ping probe
              the attacked host with address 10.0.0.1 to check if it's
              still alive. This also means, that we utilize 1 CPU only,
              and do not use the TX_RING, but sendto(2) packet I/O due
              to ''slow mode''.

       trafgen --dev wlan0 --rfraw --conf beacon-test.txf -V --cpus 2
              As an output device ''wlan0'' is used and put into
              monitoring mode, thus we are going to transmit raw 802.11
              frames through the air. Use the ''beacon-test.txf''
              configuration file, set trafgen into verbose mode and use
              only 2 CPUs starting from CPU 0.

       trafgen --dev em1 --conf frag_dos.cfg --rand --gap 1000us
              Use trafgen in sendto(2) mode instead of TX_RING mode and
              sleep after each sent packet a static timegap for 1000us.
              Generate packets from ''frag_dos.cfg'' and select next
              packets to send randomly instead of a round-robin fashion.
              The output device for packets is ''em1''.

       trafgen --dev eth0 --conf icmp.cfg --rand --num 1400000 -k1000
              Send only 1400000 packets using the ''icmp.cfg''
              configuration file and then exit trafgen. Select packets
              randomly from that file for transmission and send them out
              via ''eth0''. Also, trigger the kernel every 1000us for
              batching the ring frames from user space (default is
              10us).

       trafgen --dev eth0 --conf tcp_syn.cfg -u `id -u bob` -g `id -g
       bob`
              Send out packets generated from the configuration file
              ''tcp_syn.cfg'' via the ''eth0'' networking device. After
              setting up the ring for transmission, drop credentials to
              the non-root user/group bob/bob.

       trafgen --dev eth0 '{ fill(0xff, 6), 0x00, 0x02, 0xb3, rnd(3),
       c16(0x0800), fill(0xca, 64) }' -n 1
              Send out 1 invaid IPv4 packet built from command line to
              all hosts.
