I forgot to mention this patch also provides a way to fix the broken
software timestamp fallback mode of the SO_TIMESTAMPING API.
We would have to add this inline call to every MAC driver in an
appropriate spot within the hard_xmit function. It is not too pretty,
but providing this as a compile time option will promote
standardization of the SO_TIMESTAMPING API for applications.
