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.

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
