pktgen scripts

[Jesper Dangaard Brouer]

Hi Alexei,

I've cleaned up my pktgen scripts[1].  Do you think we should add them
instead of the sample scripts in "samples/pktgen/pktgen.conf-*" ?

The main difference is I'm replacing the "pgset" with functions not
needing global variable $PGDEV.  Three new functions reflect pktgen's
different components:
 * pg_ctrl()   control "pgctrl" (/proc/net/pktgen/pgctrl)
 * pg_thread() control the kernel threads and binding to devices
 * pg_set()    control setup of individual devices

I've named the sample scripts: "pktgen_sample{01,02,03}_desc.sh" in-order
to suggest a reading order.
I've also added a script named: "pktgen_bench_xmit_mode_netif_receive.sh"
which is basically your ingress benchmarking script.

Looks great!! Much better than old samples/pktgen/.
Could you add a readme file as well with few command line examples?
It wasn't obvious how '-b' and other flags are working. I guess if
somebody just tries to run them, the 'usage' function will explain
things too.
