Merge branch 'pktgen-new-scripts'
Jesper Dangaard Brouer says:
====================
pktgen: cleanups and introducing new samples/pktgen scripts
v3:
- Aborted v2 send due it was not generating diff stat
(this is a bug in stg-mail, if not in the root directory)
v2: address nitpicks from Cong Wang
- Remove useless cat's, but keep them for old pgset()
- Comment on: Due to pgctrl, cannot use exit code $? from grep
- Use arithmetic compare in pktgen_sample03_burst_single_flow.sh
This patchset is focused on making pktgen easier to use and better
documented. It contains a number of documentation updates and minor
changes to pktgen. The major contribution is introduction of common
helper function for sample scripts.
Instead of the old pgset() function, three new shell functions for
configuring the different components of pktgen are introduced:
pg_ctrl(), pg_thread() and pg_set().
The new functions correspond to pktgens different components.
* pg_ctrl() control "pgctrl" (/proc/net/pktgen/pgctrl)
* pg_thread() control the kernel threads and binding to devices
* pg_set() control setup of individual devices
Helpers also provide consistent parameter parsing across the sample
scripts.
Usage example:
./pktgen_sample01_simple.sh -i eth41 -m 00:12:C0:02:AC:5A -d 192.168.41.2
Usage: ./pktgen_sample01_simple.sh [-vx] -i ethX
-i : ($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 are borrowed from:
