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. |

Support for WIZnet W5100 chips. |

|
|
W5100 is a single chip with integrated 10/100 Ethernet MAC, |
|
PHY and hardware TCP/IP stack, but this driver is limited to |
|
the MAC and PHY functions only, onchip TCP/IP is unused. |
|

To compile this driver as a module, choose M here: the module |
|
will be called w5100. |
