Hi Richard,

Looking at that link, I'm only seeing that message, with none of
the patches nor the discussion. Digging back in my mailbox, I
find that the patches weren't threaded to the cover message, which
makes it quite difficult to go back and review the discussion.

Patch 1 (no comments)
https://lore.kernel.org/netdev/20220103232555.19791-2-richardcochran@gmail.com
Patch 2 (one comment from me suggesting moving a variable)
https://lore.kernel.org/netdev/20220103232555.19791-3-richardcochran@gmail.com
Patch 3 (lots of comments)
https://lore.kernel.org/netdev/20220103232555.19791-4-richardcochran@gmail.com
Patch 4 (no comments)
https://lore.kernel.org/netdev/20220103232555.19791-5-richardcochran@gmail.com

Looking back briefly at the discussion on patch 3, was the reason
this approach died due to the request to have something more flexible,
supporting multiple hardware timestamps per packet?
