OK, what I understand was `verbose` is not for just dumping Rx/Tx packets, it is a log level for testpmd. But OK it seems it only used for printing packets and only level 0 & 1 used, so agreed there won't be any issue to use verbose for this purpose. But Raslan, can you please document this somewhere proper in testpmd documentation, this information shouldn't be available only commit log.
