This was my oversight, I had asked Vasumathi to specify whether there were any link class or media restrictions for the properties, which led to the DL_ETHER specification. In fact, I think (and Vasumathi can correct me) that the property shows up for links that have drivers that support the property, regardless of class or media (i.e., they don't return ENOTSUP in their mac property callbacks). -Seb
