    initial v1  
    1010The default setting is described as follows. If a device supports function level reset (FLR), ESX always uses FLR. If the device does not support FLR, ESX next defaults to link reset and bus reset in that order. Link reset and bus reset might prevent some devices from being assigned to different virtual machines, or from being assigned between the VMkernel and virtual machines. In the absence of FLR, it is possible to use PCI Power Management capability (D3 to D0 transitions) to trigger a reset. Most of the Intel NICs and various other HBAs support this mode. 
    1111----------------------- 
    12 So there are other ways of resetting hardware to be used for passthrough than the FLR, namely d3d0, link and bridge. I think these features are based on the ACPI power management which allows for turning of individual pieces of hardware.
