I was really talking about the IXP465 with its PTP function. The Intel
devel board had a silicon bug making the PTP function useless. But
even if the bug got fixed, still the PTP function was very limiting.

I never got any feedback about the IXP465 PTP stuff, and so I doubt
whether anyone is really using the Linux PTP driver on the IXP465, but
you never know.

Thanks,
Richard
