In order to enable RX and TX logging, corresponding config options should be set at compile time. For example, if you want to enable RX/TX logging for IXGBE driver, here's a rough list of steps you need to do: 1) create a custom config file in config/ directory. Copy whatever it is that you're using for your application (e.g. defconfig_x86_64-native-linuxapp-gcc), and name it something starting with defconfig_ (e.g. defconfig_myconfig) 2) Set CONFIG_RTE_LIBRTE_IXGBE_DEBUG_RX and CONFIG_RTE_LIBRTE_IXGBE_DEBUG_TX (and whatever other options you may need, see [1] and [2]) to "y" in your custom config 3) do "make config T=myconfig && make" (or whatever other command you use to build/install DPDK - make sure to specify your custom config as target) After that, you should be able to see RX/TX logs in DPDK applications.
