+SXE Poll Mode Driver
+======================
+
+The SXE PMD (librte_pmd_sxe) provides poll mode driver support
+for Linkdata 1160-2X 10GE Ethernet Adapter.
+
+
+Configuration
+-------------
+
+Dynamic Logging Parameters
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+One may leverage EAL option "--log-level" to change default levels
+for the log types supported by the driver. The option is used with
+an argument typically consisting of two parts separated by a colon.
+
+SXE PMD provides the following log types available for control:
+
+- ``pmd.net.sxe.drv`` (default level is **DEBUG**)
+
+  Affects driver-wide messages unrelated to any particular devices.
+
+- ``pmd.net.sxe.init`` (default level is **DEBUG**)
+
+  Extra logging of the messages during PMD initialization.
+
+- ``pmd.net.sxe.rx`` (default level is **DEBUG**)
+
+  Affects rx-wide messages.
+- ``pmd.net.sxe.tx`` (default level is **DEBUG**)
+
+  Affects tx-wide messages.
+------------------------------
+
+Refer to the document :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
+for details.
