>     The first column gives the device name, unit number, and selector.  If
>     there is no device configured in the kernel for the PCI device in ques-
>     tion, the device name will be ``none''.  Unit numbers for unconfigured
>     devices start at zero and are incremented for each unconfigured device
>     that is encountered.  The selector is in a form which may directly be
>     used for the other forms of the command.  The second column is the
> class
>     code, with the class byte printed as two hex digits, followed by the
> sub-
>     class and the interface bytes.  The third column gives the contents of
>     the subvendorid register, introduced in revision 2.1 of the PCI
> standard.
>     Note that it will be 0 for older cards.  The field consists of the card
>     ID in the upper half and the card vendor ID in the lower half of the
>     value.

>     The fourth column contains the chip device ID, which identifies the
> chip
>     this card is based on.  It consists of two fields, identifying the chip
>     and its vendor, as above.  The fifth column prints the chip's revision.
>     The sixth column describes the header type.  Currently assigned header
>     types include 0 for most devices, 1 for PCI to PCI bridges, and 2 for
> PCI
>     to CardBus bridges.  If the most significant bit of the header type
> reg-
>     ister is set for function 0 of a PCI device, it is a multi-function
>     device, which contains several (similar or independent) functions on
> one
>     chip.
