+Rx adapter support
+~~~~~~~~~~~~~~~~~~
+
+Using the same mempool for all the ethernet device ports connected to
+event device would cause back pressure to be asserted only on the first
+ethernet device.
+Back pressure is automatically disabled when using same mempool for all the
+ethernet devices connected to event device to override this applications can
+use `force_rx_bp=1` device arguments.
+Using unique mempool per each ethernet device is recommended when they are
+connected to event device.
