+ * NFP PMD just requires two fixed slots, one for configuration BAR,
+ * and another for accessing the hw queues. Another slot is needed
+ * for setting the link up or down. Secondary processes do not need
+ * to map the first two slots again, but it requires one slot for
+ * accessing the link, even if it is not likely the secondary process
+ * starting the port. This implies a limit of secondary processes
+ * supported. Due to this requirement and future extensions requiring
+ * new slots per process, only one secondary process is supported by
+ * now.
