Seems strange

I installed Total Security on my Acer E5 and and in Bitdefender Central under this laptop it says Vendor:Quanta Computer Inc. , MAC Address:54:AB:3A:AA:7A:A1

and this Mac address is the one for my PCLe GbE Family Controller which has nothing connected to it. I'm curious why my laptop would be described as a Quanta Computer and identified by the Ethernet controller.
