All of the expanded 'vendor', 'device', 'class' and 'subclass' information is present in the non -v version of the command output. The numbers shown earlier can be used to derive the text information:


   class=0x010400
     determines the class/subclass lines, using the table from here:
     http://fxr.watson.org/fxr/source/dev/pci/pci.c#L1340

   card=0xc0351044 chip=0xa5111044
     these make up the vendor and device lines, using the list in
     /usr/share/misc/pci_vendors (which is derived from the PCIDEVS.TXT
     listing).

     The last 4 hex digits of the card and chip lines are the vendor ID
     while the first 4 are the device ID. The card is often given by
     the vendor, while the chip identifies the actual part it uses to
     implement functionality. For instance, a Netcomm ethernet NIC may
     use a Realtek 8139 chip... so chip gives us the fact it's
     essentially a generic Realtek chipset, while the card tells us the
     vendor who manufactured the card & perhaps their name for it.

In short, there's no reason to have to transmit all the text names back to any server -- this can all be resolved at the server end,

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

[EMAIL PROTECTED]:10:0:        class=0x020000 card=0x0027a0a0 chip=0x813910ec 
rev=0x10 hdr=0x00

Translates to:

[EMAIL PROTECTED]: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?
