+- **Secondary Processes**
+
+  Rx and Tx are not supported for secondary processes due to the single-producer
+  single-consumer nature of the AF_XDP rings. However other operations including
+  statistics retrieval are permitted.
+  The maximum number of queues permitted for PMDs operating in this model is 8
+  as this is the maximum number of fds that can be sent through the IPC APIs as
+  defined by RTE_MP_MAX_FD_NUM.
