I use genkernel to compile kernel on gentoo. How do I choose kernel configuration. Gentoo Handbook http://www.gentoo.org/doc/en/genkernel.xml says:
Device Drivers --->
Networking Support --->
Ethernet (10 or 100Mbit) --->
[*] Ethernet (10 or 100Mbit)
<*> the driver for your network card
Where should I choose these options?
