Alright, Richard can I continue your work on it and send new revisions of your
patch series or do you prefer to continue on your own?
Also your series rise the question of which timestamping should be the default,
MAC or PHY, without breaking any past or future compatibilities.
There is question of using Kconfig or devicetree but each of them seems to have
drawbacks:

Do you or Russell have any new thought about it?
