Index #1: Found a Intel i82562 Pro/100 V adapter at 0x1000.
i82557 chip registers at 0x1000:
01000000 00000000 00000000 00080002 1821782d 00000000
No interrupt sources are pending.
The transmit unit state is 'Idle'.
The receive unit state is 'Idle'.
This status is unusual for an activated interface.
The Command register has an unprocessed command 0100(?!).

ahora, la informaci�n que me arroja el ifconfig y otras aplicaciones es
una info fake, como podemos ver eeprom100-diag muestra la
verdadera MAC osea la informaci�n de la EEPROM
eepro100-diag --help
Usage: eepro100-diag [-aDfrRvVw] [-AF <speed+duplex>] [-#<BoardNum>]
Show the internal state of a network adapter.
The common usage is
eepro100-diag -aem
Frequently used options are
-a --show_all_registers Print all registers.
-e --show-eeprom Dump EEPROM contents, "-ee" shows the details.
-m --show_mii Print the MII transceiver state
Using -mm monitors the link.
-f --force Perform operation, even on a running NIC.
To operate on a single NIC, or one that hasn't been automatically found:
-# --card_num INDEX Operate on the specified card index.
-p --port-base IOADDR Assume an adapter at the specified I/O address.
-t --chip-type TYPE Specify adapter type (with '-p'), use '-1' to list.
To change the persistent EEPROM settings
-G --parameters PARMS Set adapter-specific parameters.
-H --new-hwaddr 01:23:45:67:89:ab
Set a new hardware station address. Typically disabled for safety.
-w --write-EEPROM Actually write the new settings into the EEPROM.
-D --debug
-v --verbose Report each action taken.
-V --version Emit version information.
-A --advertise <speed|setting> (See the mii-diag manual page.)

Index #1: Found a Intel i82562 Pro/100 V adapter at 0x1000.
Modifying the station (MAC) address has been disabled in this release of the diagnostic.
Use '-a' or '-aa' to show device registers,
'-e' to show EEPROM contents, -ee for parsed contents,
or '-m' or '-mm' to show MII management registers.
y pues bueno, aqui me encuentro, sigo buscando en internet.
