Oh well, I'm kinda overloaded as well (as always) and at the same time
won't work with the code during the next month due to conferences and
a vacation :z :D
Would I take this project over, I'd start working on it no sooner than
January 2024, so I don't think that would be a good idea.

Anyone else? +Cc Sabrina, there's "netdev_features_t extension"
mentioned next to her name in one interesting spreadsheet :D
