We look at it again.
Above solution can work reliably only for a very small number of PF and that too with very special hardware circuitry due to the reset flow.
Therefore, for virtualization below interface is preferred.
a. For transitional device legacy configuration register transport over AQ,
Notification to utilize transitional device notification area of the BAR.
b. Non legacy interface of transitional and non-transitional PCI device to access direct PCI device without mediation.
