Public bug reported:

Our NCCL software uses the sysfs to populate the attached topo.xml file.
Several of the entries should report "32 GT/s", but they're saying
"Unknown speed" instead. For instance:

<pci busid="0000:0c:00.0" class="0x020700" vendor="0x15b3"
device="0x1021" subsystem_vendor="0x15b3" subsystem_device="0x0082"
link_speed="Unknown speed" link_width="16">

The 5.4 kernel is missing the following commit:
