[net-next PATCH 00/10] pktgen: cleanups and introducing new samples/pktgen scripts

[Jesper Dangaard Brouer <brouer@redhat.com>]

This patchset is focused on making pktgen easier to use and better
documented. It contains a number of documentation updates and minor
changes to pktgen.  The major contribution is introduction of common
helper function for sample scripts.

Instead of the old pgset() function, three new shell functions for
configuring the different components of pktgen are introduced:
 pg_ctrl(), pg_thread() and pg_set().

The new functions correspond to pktgens 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

Helpers also provide consistent parameter parsing across the sample
scripts.

Usage example:
 ./pktgen_sample01_simple.sh -i eth41 -m 00:12:C0:02:AC:5A -d 192.168.41.2

Usage: ./pktgen_sample01_simple.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

These scripts and helpers are borrowed from:
