So I think your idea of adding current link speed/width to the "Link
Up" event is still on the table, and that does sound useful to me.

We're already reading the link status register here to check DLLA so
it would be nice. I guess if everything is healthy we're probably already
at the maximum speed by this point.

In the future we might add another tracepoint when we enumerate the
device and know the Vendor/Device ID.

I think we might have someone who would be interested in doing it.
