Re: e1000e EEPROM corruption

I found the way to run my network card without writing anything to EEPROM.

I removed NVM and MAC address checks from e1000e driver source.
The module loads fine. Ethernet adapter have MAC 00:00:00:00:00:00.
Than I change MAC to correct one by ifconfig eth0 hw ether.
Network works fine. I could even read correct data by ethtool -e.
It makes the problem more strange. The correct EEPROM is there but...

Looks like a hardware issue to me. Cold/broken solders (reflowing the board
could fix it), for example.

I have access to the same laptop, so I can get correct EPROM contents.
Still I don't know how to put this to my card.

Could you tell me how to reprogram my card?
That would only help if the problem is a "weak programming" of the EEPROM,
which is something I have never seen before. Writing to it with flacky
circuitry is probably going to crap it for good.
