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? -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
