Thanks Josh,
My mistake. I was looking at the "get" not "set" function. However, this is
still not the right fix for the driver as the actual problem is the missing
code that is supposed to be calling that function in igb_get_eee in
igb_ethtool.c. The function needs to stay. I will submit the correct fix ASAP.
Thanks,
Carolyn
