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.
