Some general notes:

• A change like this first needs to be proposed for the master branch. Once it has been merged, it can be considered for release branches like openwrt-21.02.
• Your commit message(s) need to have the correct formatting. In this case, you will also need to squash your commits.
• You will need to update PKG_RELEASE.
• And you will want to ping the package maintainer, in this case @commodo
