Hi David,
The UEFI spec defines the format of an NVMe device node, I think the
driver (maybe on the NVME option rom) that produces the device path for
the NVME device should get updated to follow the spec.
For those vendor defined paths, I think the DevicePathLib will only dump
the hex of device node content. There is no method to extract the
information from them since they are not documented in the UEFI spec.
Best Regards,
Hao Wu
