When a hwprov timestamping source is changed, but without updating the timestamping parameters, we may want to reconfigure the timestamping source to enable the new provider. This is especially important if the same HW unit implements 2 providers, a precise and an approx one. In this case, we need to make sure we call the hwtstamp_set operation for the newly selected provider.
