Name: Realtek RTL8151GH-CG 10/100/1000
Please post the HP laptop model instead of the Realtek card name.
According to HP service manual for this notebook:
this Realtek Ethernet module is shared among at least 4 different (AMD/Intel) mainboards. That is why it does not have subsystem id of particular mainboard it is used universally among them.
Name: ProBook 450/455
The card might well exist on different motherboards but as far as I can see in that PDF document, they are motherboards for the ProBook 450/455 laptops. Unless you have any evidence that the subsystem also exists on laptops that aren't a ProBook 450/455, I'll leave it this way.
Please don't put your own name into the Name field, however.
