Not sure. I had no problems with the PCIe cards I tested with the current 
code. But from my experience, this card reset behavior is highly card/device 
dependent.

It would be good to know that this new code doesn't break detection of other 
PCIe cards/devices. Prashant, did you check this new code with other PCIe 
cards/devices as well? If this patch doesn't break other PCIe cards like the 
Intel PRO/1000, then:
