If you have an Acorn system with one of these network cards, you
should say Y to this option if you wish to use it with Linux.

-config ARM_ETHER00
- tristate "Altera Ether00 support"
- depends on NET_ETHERNET && ARM && ARCH_CAMELOT
- help
- This is the driver for Altera's ether00 ethernet mac IP core. Say
- Y here if you want to build support for this into the kernel. It
- is also available as a module (say M here) that can be inserted/
- removed from the kernel at the same time as the PLD is configured.
- If this driver is running on an epxa10 development board then it
- will generate a suitable hw address based on the board serial
- number (MTD support is required for this). Otherwise you will
- need to set a suitable hw address using ifconfig.
