Trap PCI calls from driver

Hi all,

My query is related to ESXi device drivers and ESXi PCIe subsystem.

I am writing a NIC driver for ESXi and this NIC hardware is still in its design phase. We have a binary on a remote machine that emulates the firmware of this NIC.

Is there a way to trap the PCI calls from the ESXi driver module so that they can be sent to this remote binary?

Thanks in advance.
