From: Xuelin Shi <forrest....@linaro.org>
This patch made the following changes:
- receiving packets from multiple pktios other than generating packets
- identifying TM user by ip with individual class of service
- print the user service while starting the program
- pirnt the packets counts every 10 seconds for each user
Signed-off-by: Xuelin Shi <forrest....@linaro.org>
