[meta-intel] [yocto] jasperforest ethtool package usage

[Eddy Lai GMail]

Hi

I use yocto 1.3 with jasperforest BSP, on my target Xeon board there's 
Intel 82580DB gigabit ethernet controller,
have add the "CORE_IMAGE_EXTRA_INSTALL += "ethtool"" in my local.conf , 
build and boot the image from USB flash disk,
but got "Bad address" error when I try to use "ethtool -E" command, the 
EEPROM on my board is ST25256
will the "ethtool" need to be ported for using on different size EEPROM? 
or should I made modification to igb driver?
