Yes, I had noticed that it is part of intel-1xxxx feature also. I tend to think that it is better to separate out CONFIG_E100 option from intel-1xxxx I think that platforms that want 1G/10G enabled would not need 10/100 driver

I'm wondering whether we want to break them up or at least create a separate e100 feature. > BTW what does a message such as following in the .config file mean ? > > "CONFIG_xxxxx is not set" > It means that config option was never set or got turned off because of unmet depencies.
