+void

+
+	TAILQ_INSERT_TAIL(&rte_bus_list, bus, next);
+	RTE_LOG(INFO, EAL, "Registered [%s] bus.\n", bus->name);

I think it should be a debug log.

+/* unregister a bus */
+void
+rte_bus_unregister(struct rte_bus *bus)

I appreciate the effort for commenting, but I think the function name
is self describing.

+/**
+ * @file
+ *
+ * RTE PMD Bus Abstraction interfaces

RTE PMD?
I would say "DPDK device bus interface"

+DPDK_17.02 {
+	global:
+
+	rte_bus_list;

Why the bus list is exported?
If it is for testing purpose, I wonder wether it is worth to do it.
