Alright, Richard can I continue your work on it and send new revisions of y= our patch series or do you prefer to continue on your own? Also your series rise the question of which timestamping should be the defa= ult, 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: https://lore.kernel.org/netdev/ad4a8d3efbeaacf241a19bfbca5976f9@walle.cc/=20 Do you or Russell have any new thought about it?
