# # WIZnet devices configuration # config NET_VENDOR_WIZNET bool "WIZnet devices" depends on HAS_IOMEM default y ---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. if NET_VENDOR_WIZNET config WIZNET_W5100 tristate "WIZnet W5100 Ethernet support" depends on HAS_IOMEM ---help--- 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. config WIZNET_W5300 tristate "WIZnet W5300 Ethernet support" depends on HAS_IOMEM ---help--- Support for WIZnet W5300 chips.
