information was missing. The solution was to use the classId, which is 0x0200 for NICs, as a filter on the HostPciDevice objects that are present under the pciDevice property in the HostHardwareInfo object.
That made me think that this would be an ideal way to list all the hardware present on a server. But to my surprise a lot of the entries are listed as “unknown”. Since the vendorId and the deviceId are known I knew that this could be improved.
