34 Pre-Installation Configuration
35 ------------------------------
40 The following build-time options may be enabled on build time using.
42 ``-Dc_args=`` meson argument (e.g. ``-Dc_args=-DRTE_LIBRTE_TXGBE_DEBUG_RX``).
44 Please note that enabling debugging options may affect system performance.
46 - ``RTE_LIBRTE_TXGBE_DEBUG_RX`` (undefined by default)
48 Toggle display of receive fast path run-time messages.
50 - ``RTE_LIBRTE_TXGBE_DEBUG_TX`` (undefined by default)
52 Toggle display of transmit fast path run-time messages.
54 - ``RTE_LIBRTE_TXGBE_DEBUG_TX_FREE`` (undefined by default)

58 Dynamic Logging Parameters
59 ~~~~~~~~~~~~~~~~~~~~~~~~~~
61 One may leverage EAL option "--log-level" to change default levels
62 for the log types supported by the driver. The option is used with
63 an argument typically consisting of two parts separated by a colon.
65 TXGBE PMD provides the following log types available for control:
67 - ``pmd.net.txgbe.driver`` (default level is **notice**)
69 Affects driver-wide messages unrelated to any particular devices.
71 - ``pmd.net.txgbe.init`` (default level is **notice**)
73 Extra logging of the messages during PMD initialization.
