Subject: [PATCH net-next RFC 5/5] net-timestamp: tx timestamping default mode flag

From: Willem de Bruijn <willemb@...gle.com>

The number of timestamping points along the transmit path has grown,
as have the options. Preferred behavior is to request timestamps with
ID, without data (which enables batching) and for all supported
timestamp points. Define a short option that enables all these
defaults.
