Re: [PATCH v2 2/4] PCI: Revert to the original speed after PCIe failed link retraining

[Matthew W Carlis]

Sorry past few days have been struggling to buy some time to look at these. Every
time I go into the store and ask for more time they try to give me phone cards.
Its an improvement to restore the "capable" link speed & in this case I think we're
also enabling a user to have over-ridden it if they were to write the register
by hand. Its nice to give every potentially "new" device a chance at achieving
its full potential.
A little outside of the scope of this patch, but I was wondering if the logline
should be a warn level logline? I don't honestly know what a "normal" level is
for the pci system. Also, instead of saying  "retraining ... at 2.5GT/s\n",
would it be more clear if it said "forcing downstream link to 2.5GT/s". In my mind
its more clear that an action has been taken which produces a potentially less
than unexpected speed.

I can test this patch on a couple of systems, but I need a week or so to
get it done...
