This is useful when the switch is directly connected to the > host MAC interface. 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? Andrew
