why IRP_MN_REMOVE_DEVICE?

Hi

When I disable a virtual NIC which enumerated by my PCI bus driver, I
receive a IRP_MN_REMOVE_DEVICE IRP not IRP_MN_STOP_DEVICE in my bus driver?
Any info which I provide to PnP manager in my bus driver is wrong?

Thanks
Wayne

Stop is only sent on a pnp rebalance, remove is sent on disable so you are seeing the correct behavior.

Yes, got it. My fault in driver is to really remove PDO in bus driver.
But if I scan hardware, such PDO will be enumerated by bus driver.
That’s why my bus driver cannot work properly. So now, I update bus
driver to enhance enumeration mechanism for child device. Works well now.
