Hi, When I boot my Jetson TK1, by default I get this from lspci:
00:02.0 PCI bridge: NVIDIA Corporation TegraK1 PCIe x1 Bridge (rev a1) 01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 0c) If however I plug some mini PCIe card, I get this instead: 00:01.0 PCI bridge: NVIDIA Corporation TegraK1 PCIe x4 Bridge (rev a1) 00:02.0 PCI bridge: NVIDIA Corporation TegraK1 PCIe x1 Bridge (rev a1) 01:00.0 Network controller: MEDIATEK Corp. Device 7612 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 0c) I.e., there is a new Tegra PCIe x4 bridge and the number of the previous x1 bridge changed. That is ugly because it changes the ID of the on-board PCI NIC from 01:00.0 to 02:00.0, which on openSUSE renames the network interface from enp1s0 to enp2s0, so that my /etc/sysconfig/network/ifcfg-enp1s0 does not take effect and the network interface doesn't come up. Tested with U-Boot v2016.05 and v2016.07 and kernel 4.6.2 and 4.7-rc6. Shouldn't U-Boot or the kernel driver always configure the PCIe ports the same way (both bridges available) since the slot is always there on this board?
