Hi,

I need to get an output that is the same as "ethtool -e eth0"

But I need to use another method that does not use the eth port ID (ethX).
Does anyone know of any method?

Thanks!!

Did you try lspci in verbosest mode?

hmmm

ethtool -e eth0

returns this kind of log:

can lspci show this kind of log?

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:

$ 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.
