From 6e32a74a6f151c3e64d7d79e54948b8938be2cdc Mon Sep 17 00:00:00 2001 From: Daniel T. Lee Date: Sat, 29 Jun 2019 22:33:58 +0900 Subject: samples: pktgen: allow to specify destination port Currently, kernel pktgen has the feature to specify udp destination port for sending packet. (e.g. pgset "udp_dst_min 9") But on samples, each of the scripts doesn't have any option to achieve this. This commit adds the DST_PORT option to specify the target port(s) in the script. -p : ($DST_PORT) destination PORT range (e.g. 433-444) is also allowed Signed-off-by: Daniel T.
