I was wrong here, sorry -- the fix for one of the issues discussed in
this thread is still just in next as ff8a969f7dc8e7 ("PCI: Skip Target
Speed quirk on clamped ports with no link").

I think it's time we get new mailing list threads for any problems that
still remain with ff8a969f7dc8e7, because when you wrote "I noticed
another report" earlioer at least I have no idea which of the two
problems discussed in this thread you mean; but maybe it's better to
start new threads only once 7.4-rc1 is out with testing based on that,
as that will contain the aforementioned and other fixes and likely is a
good new starting point for further discussions.

Ciao, Thorsten
