default y
depends on ARCH_GEMINI
---help---
If you have a network (Ethernet) card belonging to this class, say Y
and read the Ethernet-HOWTO, available from
<http://www.tldp.org/docs.html#howto>.
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 D-Link devices. If you say Y, you will be asked for
your specific card in the following questions.
if NET_VENDOR_GEMINI
config GEMINI_SL351X
tristate "StorLink SL351x Gigabit Ethernet support"
depends on ARCH_GEMINI
select PHYLIB
select MDIO_BITBANG
select MDIO_GPIO
select CRC32
---help---
This driver supports StorLink SL351x (Gemini) dual Gigabit Ethernet.
