Method for updating EEPROM in a 10 GbE Controller 82599

Hi !

I use a 10 GbE Controller 82599EN. I need to update an EEPROM which is programed via ROM Writer.

I try to update by using ethtool.

Type as below:

ethtool -E eth2 magic 0x10FB0860 offset 0x0 length 0x1 value 0x07

Result as below:

Cannot set EEPROM data:Invalid argument.

Would you tell me what are invalid arguments ?

Or Would you tell another method for updating an external EEPROM ?

BR,

Taira

Hi !!

I understand why does ethtool command occur the error message(Invalid argument).

I used incorrect magic number in case of using ethtool -E option.

The magic number should be "Device ID + Vender ID", but I set "Vender ID + Device ID".

I input correct magic number, and success to update EEPROM contents.
