Why do you need this when no other board does? Why is your board
special?

As i said before, i'm guessing your board has back to back PHYs
between the SoC and the switch and nobody else does. Is that the
reason why? Without this, nothing is configuring the switch MAC to the
results of the auto-neg between the two PHYs?

Or am i completely wrong?
