Hello, within my project I created a web demo using the AT91SAM7x256,
the demo uses an EMAC driver not related to the ATMEL code and it uses
both the transmit and receive interrupt sources.
I hope this can help.
The driver is under ./ports/ARM7-AT91SAM7x256
The demo works on an Olimex board that uses a Micrel PHY, the driver may
require small changes if your board uses a different PHY.
