Which mac instances support timestamping in ethernet library Topic is solved

[gerrykurz]

While looking at the code to see what the ifnum parameter does, it looks like the normal 100 mbps ethernet implementation does not support time-stamping. Is this correct?From the user guide, there is this statement:"Additional API calls are available in the configuration interface of the real-time MACs that will cause a run-time assertion if called by the non-real-time configuration."However, it is not specified what API calls work with the real time MAC and not with the non-real-time configuration.As an aside, what does the ifnum parameter do? From looking at the code, it seems like it does nothing. Is this the case?

Yes this is correct. Only the real-time MAC instances support timestamping. 

The ifnum parameter is not currently used but is reserved for potential use in future versions of the MAC.

Can you please update the user guide to reflect these answers so as to help other developers.
