+ * RTE Mellanox PCI Bus Interface
+ * Mellanox ConnectX PCI device supports multiple class (net/vdpa/regex)
+ * devices. This bus enables creating such multiple class of devices on a
+ * single PCI device by allowing to bind multiple class specific device
+ * driver to attach to mlx5_pci bus driver.
