- 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.

- your boot loader (lilo or loadlin) about how to pass options to the
- kernel at boot time.)
