2 # WIZnet devices configuration
5 config NET_VENDOR_WIZNET
10 If you have a network (Ethernet) card belonging to this class, say Y.
12 Note that the answer to this question doesn't directly affect the
13 kernel: saying N will just cause the configurator to skip all
14 the questions about WIZnet devices. If you say Y, you will be asked
15 for your specific card in the following questions.
20 tristate "WIZnet W5100 Ethernet support"
23 Support for WIZnet W5100 chips.
25 W5100 is a single chip with integrated 10/100 Ethernet MAC,
26 PHY and hardware TCP/IP stack, but this driver is limited to
27 the MAC and PHY functions only, onchip TCP/IP is unused.
29 To compile this driver as a module, choose M here: the module
33 tristate "WIZnet W5300 Ethernet support"
36 Support for WIZnet W5300 chips.
38 W5300 is a single chip with integrated 10/100 Ethernet MAC,
39 PHY and hardware TCP/IP stack, but this driver is limited to
40 the MAC and PHY functions only, onchip TCP/IP is unused.

46 prompt "WIZnet interface mode"
47 depends on WIZNET_W5100 || WIZNET_W5300
48 default WIZNET_BUS_ANY
50 config WIZNET_BUS_DIRECT
51 bool "Direct address bus mode"
53 In direct address mode host system can directly access all registers
54 after mapping to Memory-Mapped I/O space.
56 config WIZNET_BUS_INDIRECT
57 bool "Indirect address bus mode"
59 In indirect address mode host system indirectly accesses registers
60 using Indirect Mode Address Register and Indirect Mode Data Register,
61 which are directly mapped to Memory-Mapped I/O space.
64 bool "Select interface mode in runtime"
66 If interface mode is unknown in compile time, it can be selected
67 in runtime from board/platform resources configuration.
69 Performance may decrease compared to explicitly selected bus mode.
