Send pull requests to openwrt/packages, I guess.

Where else pull? git?
Please tell us more about your software.
If people like it then send pull request. If liked, more chance it will get into Lede/Openwrt

You can also set up your own repository if that's something which is specific to your institution and doesn't need to be included in the official luci/packages repos.
