Be targeted at the net tree Subject: [PATCH net] ... 2. Be CCed to stable 3. Have a fixes tag. Perhaps this one? Fixes: cf26df8833cc ("net: ethernet: mtk_eth_wed: add mtk_wed_configure_irq and mtk_wed_dma_{enable/disable}") I'm unsure if the maintainers would like a repost because of this. But at any rate, please keep it in mind for the future. More information on the netdev development processes can be found here: https://docs.kernel.org/process/maintainer-netdev.html The above not withstanding, this looks good to me.
