0011 If you have a network (Ethernet) card belonging to this class, say Y.

0013 Note that the answer to this question doesn't directly affect the
0014 kernel: saying N will just cause the configurator to skip all
0015 the questions about WIZnet devices. If you say Y, you will be asked
0016 for your specific card in the following questions.
