There are "git format-patch" or "git send-email" argument to do this easily - Keep a changelog in the patch, as a note (after "---" in the commit log), like: Signed-off-by: ... --- V3: * Added this, removed that v2: * Rewrite from scratch - Keep all version of your patches in same email thread, this can be done via "git sent-email", '--in-reply-to' argument, please check documents. This helps to keep all version and change requests and changes grouped, so makes it easy to manage. Also for archives, it makes easier to find out all versions and see the stages of improvement, otherwise it is very hard to trace a past feature from archives. And as far as I got, last patch you send makes the API experimental, but the API is for drivers (not applications), so it should be defined in 'ethdev_driver.h' and marked as internal, also in INTERNAL group. (I already commented this one of the other version of the patch) Another thing is, there are some checkpatch warnings, you can see check results in the "Checks" box of: https://patches.dpdk.org/project/dpdk/patch/20220121042944.23929-1-kumaraparamesh92@gmail.com/ The "ci/checkpatch" test is colored as yellow, if you click it you will see the warning. And I am pretty sure internal tool './devtools/check-git-log.sh' will have a few things to complain. Can you please solve above checkpatch and check-git-log warnings in next version? Thanks, ferruh
