I don't think you can dump EEPROM from raw PCI. It wouldn't work the same way for each and every kind of network card; that's why it's the job of the network driver.

Are you on Linux? You can tell which interface is on what bus:

Code:

$ ls -l /sys/class/net/

total 0
lrwxrwxrwx 1 root root 0 Apr 17 13:00 lan -> ../../devices/pci0000:00/0000:00:0a.0/net/lan
lrwxrwxrwx 1 root root 0 Apr 18 11:14 lo -> ../../devices/virtual/net/lo
lrwxrwxrwx 1 root root 0 Apr 18 11:14 sit0 -> ../../devices/virtual/net/sit0
lrwxrwxrwx 1 root root 0 Apr 18 11:14 tun0 -> ../../devices/virtual/net/tun0

$

You can se that lan(what I've renamed eth0 into) is on pci0000:00/0000:00:0a.0. From that you can decide which interface to feed into ethtool.

eap

EAP(4)							   BSD Kernel Interfaces Manual 						    EAP(4)

NAME

     eap -- AudioPCI audio device driver

SYNOPSIS

     eap*   at pci? dev ? function ?
     audio* at audiobus?
     joy*   at eap?
     midi*  at eap?
     options EAP_USE_BOTH_DACS

DESCRIPTION

     The eap driver provides support for the Ensoniq AudioPCI and Creative Labs SoundBlaster PCI series of audio cards.  All models based on the
     ES1370, ES1371, and ES1373 chips are supported.

     By specifying:

	   options EAP_USE_BOTH_DACS

     a second audio device is attached.  You can use it simply by directing audio output to it.  This way it is possible for two different pro-
     grams to use the "same" audio device simultaneously.

SEE ALSO

     ac97(4), audio(4), joy(4), midi(4), pci(4)

HISTORY

     The eap device driver appeared in NetBSD 1.4.

CAVEATS

     The joystick port hardware works by emulating a legacy isa(4) joystick port, bypassing the pci(4) bus method for address allocation.  This is
     unlikely to work on PCI busses other than the primary one.  There is also a possibility for conflicts with real ISA devices because the PCI
     bus is probed before ISA.	Use with caution.
