help
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.

help
In direct address mode host system can directly access all registers
after mapping to Memory-Mapped I/O space.
config WIZNET_BUS_INDIRECT
bool "Indirect address bus mode"
help
In indirect address mode host system indirectly accesses registers
using Indirect Mode Address Register and Indirect Mode Data Register,
which are directly mapped to Memory-Mapped I/O space.

bool "Select interface mode in runtime"
help
If interface mode is unknown in compile time, it can be selected
in runtime from board/platform resources configuration.
Performance may decrease compared to explicitly selected bus mode.

help
In SPI mode host system accesses registers using SPI protocol
(mode 0) on the SPI bus.
Performance decreases compared to other bus interface mode.
In W5100 SPI mode, burst READ/WRITE processing are not provided.
To compile this driver as a module, choose M here: the module
will be called w5100-spi.
