> Vou trocar essa placa de rede , vc sabe o que significa esse card ?

Vivendo e aprendendo, fiquei curioso e fui reler o man pra lembrar o
que era o card, pois o que eu sempre uso é o chip, então descobri
que é normal pra placas velhas o card=0x00000000, segue o trecho
do man pciconf

     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.
