Gotta start somewhere ... how many of us are really out there?

'k, looking at the above, and comparing it to what I'm getting from 
pciconf -l, I'm missing something ... namely:

none8 at pci2:10:0:        class=0x020000 card=0x0027a0a0 chip=0x813910ec rev=0x10 hdr=0x00

Translates to:

none8 at pci2:10:0:        class=0x020000 card=0x0027a0a0 chip=0x813910ec rev=0x10 hdr=0x00
     vendor   = 'Realtek Semiconductor'
     device   = 'RT8139 (A/B/C/810x/813x/C+) Fast Ethernet Adapter'
     class    = network
     subclass = ethernet


But, the last 4 hex of card/chip aren't teh same ... oh, wait, re-reading 
what you stated, is it safe to assume that chip= can be ignored ... nope, 
that doesn't follow either ... but I think I see it ...

For the above, vendor *should* be Aopen Inc, not Realtek Semiconductor ...

'k, so, for the above:

card=0x0027a0a0
 	- Aopen Inc (A0A0)

chip=0x813910ec
 	- Realtek Semiconductor (10EC)
 	- 8139    RT8139 (A/B/C/810x/813x/C+) Fast Ethernet Adapter (8139)

And the 0027 is actually meaningless in this case ...

So, what I'm looking for is vendor->device, but in some card= cases, there 
won't be a 'Device' listed ...

As to class= ... what table am I supposed to be seeing at that URL?
