4.18. Configuration Retry Status Enable
The application layer can use the Configuration Retry Control register (CFG RETRY CTRL) to update the per PF Configuration Retry Status Enable controls (CRS En Controls) driven to the HIP. All VFs share the same control as their parent PF. When the corresponding PF's CRS En Control is asserted, HIP responds to Configuration TLPs with a CRS (Configuration Retry Status) if it has not already responded to a Configuration TLP with non-CRS status since the last reset. You can use this to hold off on enumeration.
