You are most likely right.
using  ipd_port+1 is probably what made my eth0 show up on the 2nd RJ45 
port.
We were just using those boxes for early development, to verify basic 
Octeon functionality of some of our hardware drivers, so once an 
Ethernet port started working, I did not look into it any further, since 
it was a temporary setup just to get things going.

I looked for the original source from Movidis, and all I found in their 
kernel source were broken symlinks to a tool chain they that they did 
not give me :-(
