'lan8814' is not a vendor and the format for properties is
<vendor>,<propname>.

Is this configuration or lack of h/w feature? IOW, instead of 'will
not', 'does not' or 'timestamping is disabled.'. As configuration, that
seems like common property. For (lack of) h/w features, that should be
implied by the compatible or VID/PID.

s/_/-/

What are the units here? Is this a common feature of PHYs?
