Xilinx LLTEMAC driver issues

Hi John,
Thanks for the very fast reply! Right now I'm not at work so I don't
have the board or EDK here to test anything.
I'm using checksum offload, but I don't know if DRE is enabled or not. I
can't recall seeing any setting to enable/disable DRE..
A few things that crossed my mind:
Last year I did a design with EDK 8.2, back then there was an issue with
the ML403 boards having an old revision of the FPGA which wasn't
compatible with some versions of the IP core. There are no such version
issues with the xps_ll_temac?
I don't think that I had phy-addr set in the DTS file. Will test that on
Monday.
Best regards,
Magnus

I have done limited testing with powerpc arch and the LL TEMAC, but I didn't see this issue there either. Powerpc arch is definitely less mature in my experience than the ppc arch. I'll do a quick test with my powerpc arch and make sure again I'm not seeing it.
