If you wish to compile a kernel for the EBSA-110, then you should
always answer Y to this.

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.
