As a bug fix for code present in the net tree, this should
1. 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.
