 10           If you have a network (Ethernet) card belonging to this class, say Y
 11           and read the Ethernet-HOWTO, available from
 12           <http://www.tldp.org/docs.html#howto>.

 14           Note that the answer to this question doesn't directly affect the
 15           kernel: saying N will just cause the configurator to skip all
 16           the questions about WIZnet devices. If you say Y, you will be asked
 17           for your specific card in the following questions.

 29           the MAC and PHY functions only, onchip TCP/IP is unused.
