  I've figured out that backporting will be less intrusive if an update to
use `->supported_speeds' is posted as a separate follow-up change. So it
is now 2/3 in this series, after 1/3 comprising the original patch, only
trivially updated.  Then 3/3 moves the maximum link speed determination
earlier on for an early exit in the PCIE_SPEED_2_5GT case; maybe unlikely,
but essentially free now, now that we retrieve the speed anyway, and makes
code a little simpler yet.

We’re waiting on this patch. Are there any updates or plans for it?

Thanks,

This v2 patch series looks good to me. However, there has been a fairly
extensive discussion on the earlier thread linked below, and we did not
reach a clear conclusion there.

Hopefully we can resolve it soon.
