...Thanks for replying Roderick, but as I said, the PCI sniffer hardly shows anything on the chipset other than acknowledging the existence of it....
I've attached two files I use on my system, both dated 2017, take a look at this stuff.
In the meantime, granted w/o net connection that's a PITA, but what can you fish out of the PCI output?
Here is what I see on my machine, pertinent info in bold and italics:

...The Subsystem vendor number, (at least a partial one), is 10ECh
The Subsystem ID is 816910ECh...
This device ID = 8169, the 10ECH is the vendor ID, is listed several times in the files I zipped up. But as others pointed out, it references to a number of different devices.
