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/[email-masked]
Patch 2 (one comment from me suggesting moving a variable)
https://lore.kernel.org/netdev/[email-masked]
Patch 3 (lots of comments)
https://lore.kernel.org/netdev/[email-masked]
Patch 4 (no comments)
https://lore.kernel.org/netdev/[email-masked]

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?
