If you are targeting this as a fix, then: 1. Use "[PATCH net]" as subject prefix. See [1]. 2. Add a Fixes tag. 3. Please mention in the commit message that this is fixed by using the payload_template_calc_checksum() / payload_template_expand_checksum() helpers that are only available in v6.3 and newer kernels. Patch looks good otherwise (I also tested it). [1] https://docs.kernel.org/process/maintainer-netdev.html
