+- **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
