How and what type of packets are you sending? Raw MAC frames, IP? Are
you using custom code, or can you try things like ping?
If you are using IP, I trust you checked the Linux configuration (like
assigning a valid IP address to the interface and making sure the
routing table is correct).

Thomas,
I would like to thank you for your very kind assistance on the DPAA problem.
We traced the problem to the connection between MAC and PHY, and we have
resolved it by instrumenting code and comparing the TBI and PHY
initialization from u-boot to the Linux DPA code, and replacing some of the
magic numbers we found in the driver with magic numbers we know to work.
OUCH!
We spent an inordinate amount of effort in trying to understand the
undocumented code/tree, but I am convinced that the device-tree approach to
embedded boards is a very valuable approach, and will ultimately solve many
more problems than it creates short term.
Again, your information was of great assistance, and I look forward to being
able to pay forward the same kind of assistance in the future.
I'm very glad you found the issue (I was running out of ideas ;-) and
that I was able to help you in some way.
Thanks for posting back.
Good luck with the rest of your project!
Best regards,
Thomas
Cheers,
Rob Sciuk.
