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.
