- If you have a network (Ethernet) card belonging to this class, say Y.
- Note that the answer to this question doesn't directly affect the
- kernel: saying N will just cause the configurator to skip all
- the questions about WIZnet devices. If you say Y, you will be asked
- for your specific card in the following questions.

- the MAC and PHY functions only, onchip TCP/IP is unused.
- To compile this driver as a module, choose M here: the module
