Some parts of the networking stack and at least one driver test fields within the 'struct phy_device' in order to query time stamping capabilities and to invoke time stamping methods. This patch adds a functional interface around the time stamping fields. This will allow insulating the callers from future changes to the details of the time stamping implemenation.
