11	  If you have a network (Ethernet) card belonging to this class, say Y.

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