PCIe: GEN3 (8GT/s) Operation Not Supported
PCI-Express (PCIe) GEN3 (8GT/s) operation is not supported. This restriction applies to both Root Complex and Endpoint modes of operation. PCIe GEN1 (2.5GT/s) and PCIe GEN2 (5GT/s) operation is unaffected.
No workaround is available. Implement PCIe as GEN1 or GEN2 only.
