IMX6Q sabresd 使用minipcie 转PCIE-1X 接PCIE-1X 82756 网卡，PCIE linkup failed. linux-3.0.35
We have tested net card based on intel8274IT, no problem. in linux BSP, only PCIe RC driver is supported. so if you connect intel82576, you also need to add it's linux driver to bsp.
then run lspci to check if pcie device can be found.
try it, please!
Have a nice day!
