Nope! :-(
Rumour has it that Montavista is soon going to release the source for
2.6 kernel to run on Xilinx platforms.

Hello Ameet,
I too am working on this type of project. I am trying to get the xilinx
obp 10/100 mac driver into the 2.6.17.6 kernel. Unfortantly, I think I
need some of the montavista sources not generated by the xilinx
software, which only generates driver code for the 2.4 montavista
kernel. Did you happen to get an Ethernet mac going on the virtex2 or
virtex4 with the 2.6 kernel?

Thanks Ed! I did get a root fs up and running NOT using JFFS2 though.
I used ext2.
cheers,

I found your post about the Virtex II part one at
http://www.linux.get2knowmore.com. Thanks for the info. Did you
happen to get a root fs up and running using jffs2?
Best Regards,

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.

Thank you for the reply David,
I have started the montavista 10/100 enet port from the xilinx edk
generated 2.4 driver to the 2.6 driver. Unfortunately, I can't post the
driver port publicly because it's not GLP'd, as far as I know. We only
needed a 10/100 mac, so we didn't bother with a TEMAC. I got the obp and
enet directories to compile but I crash on link with an undefined reference:

I will work on this more today. If you want to send me your TEMAC code,
please do so. I can always use the reference.

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
