Mathias,

You should be able to continue using the 82574L once we get the patch
pushed upstream, which should be relatively soon.

As far as other adapters are concerned, the Intel adapter I would
recommend for PTP is the I210.

Please do not hesitate to let us know if you continue having problems.

Cheers,
Matthew
