WHQL signed IPoIB drivers are on Windows Update now. This brings to light a

<font size=2 color=black><span style='font-size:10.0pt;color:black'>The issue
is the PnP hardware id’s generated by the IB bus for virtual devices are not
version specific. This means if I install the latest IB stack build, Windows
Update will still offer to update my IPoIB drivers, even though they probably
would be incompatible with the other IB stack components. The WHQL drivers are
approximately build 614, and I know the IBAL interface has new functions and a
new version number in the current build. There is absolutely nothing to tell
Windows Update that drivers for PnP hardware id “IBA\IPoIB” in version 614 of
the IB stack will not work on a stack looking for say the 758 build of the PnP
hardware id “IBA\IPoIB”.</span></font><br>

<font size=2 color=black><span style='font-size:10.0pt;color:black'>It seems
like some version number and optionally a vendor unique id needs to be part of
all the PnP id’s generated, to assure updates only happen between compatible
components. </span></font><br>
