With the Cavium Octean3 BSP (cav-octeon3), the system may not enumerate all devices connected behind a PCIe switch. The 'lspci' command may be used to show not all devices have been enumerated. For example: Here is the output of `lspci -nn` on WRL8: root@localhost:~# lspci -nn 0001:01:00.0 PCI bridge [0604]: PMC-Sierra Inc. Device [11f8:8546] 0001:01:00.1 Bridge [0680]: PMC-Sierra Inc. Device [11f8:8546] 0001:02:00.0 PCI bridge [0604]: PMC-Sierra Inc. Device [11f8:8546] The expected output may be: ~ # lspci -nn 0001:00:00.0 PCI bridge [0604]: Cavium Networks Device [177d:9700] (rev 03) 0001:01:00.0 PCI bridge [0604]: PMC-Sierra Inc. Device [11f8:8546] 0001:01:00.1 Bridge [0680]: PMC-Sierra Inc. Device [11f8:8546] 0001:02:00.0 PCI bridge [0604]: PMC-Sierra Inc.
