Utility is very good for traffic generation, however, you may wish to
consider adding a parameter
to increase tx_queue_len for the device underneath if you choose to
inject traffic from multiple
sources into the device for testing. With the tx_queue_len set to
defaults, I see a lot of traffic
from above getting dropped when tests are running. I have had to
increase this number to
60000 to get around certain test scenarios.
Just a suggestion.
