4.1.2.2. For CvP Update Mode

Before you perform CvP update mode, the device must be in user mode.
Note: For PCIe* 4.0 capable Endpoints, in user mode, Intel® recommends to verify that the link has been trained to the expected PCIe* 4.0 rate. If the link is not operating at PCIe* 4.0, software can trigger the Endpoint to retrain.
