As @Lukas points out, link speed changes and device plug/unplug events are
orthogonal issues.

Based on this thread discussion, I believe we need additional tweaking to
introduce a new tracepoint (perhaps named PCI_LINK_EVENT) to handle
link speed changes separately.

Regarding our next steps, would it be acceptable to merge the
PCI_HOTPLUG_EVENT to mainline first, and then work on implementing
the new link event tracepoint afterward?

Yes I think so, I think this patch is ready to go in.

However I'm not part of the PCI maintainer team,
it would have to be applied by them (barring any objections).

We're now in the merge window and it may be too late to squeeze it
into the v6.16 pull request, but maybe it can be applied after
the merge window has closed (in 1 week).

Thanks,

Lukas
