Its a long pending patch.
Any decision on this patch.
Hmmm.... I really don't know what to do. IIRC it was something lifted
from the proprietary sil driver and they probably added that to work
around performance oddities under certain configurations and I'm a bit
worried about changing it after all this time. Is there any way to
make this conditional somehow?
I see that there is a patch in the latest kernel.

pci: Clamp pcie_set_readrq() when using "performance" settings
I think, this will resolve the issue.
We are moving to the new kernel. Will check it there.
I see that the patch above considers MPS to clamp RRQ size, while I think
both should be independent, or perhaps I am missing something.
Please also see following patch for completeness.
