Nope! :-( Rumour has it that Montavista is soon going to release the source for 2.6 kernel to run on Xilinx platforms.I have 2 different TEMAC's working under 2.6 with a V4. The MontaVista driver that has been posted on the list that I think is from MontaVista for the PLB TEMAC with very minor modifications to get it to work at speeds other than GigaBit. A driver I wrote for the LocalLink TEMAC that works limpingly. I have been unable to figure out how to get a receive interrupt from the LocalLink TEMAC so receives are polled and performance is poor. I have pretty much abandoned work on it - my client wants the smallest possible FPGA footprint BUTanother OS I am porting requires interrupt driven IO and we are looking for a single minimal hardware implimentation for all platforms. Anyway, if anyone wants the LL TEMAC in its current state I can post it. Currently it sends fine. It drops about 50% of all received packets - but that is probably debugging overhead and poll rate tuning.
I would be interested looking at the LL TEMAC patch. Hopefully I can pick up where you left off. We would require an interrupt driven TEMAC
