I feel like I have seen this idea before. Is this your first posting?
Would you mind including links to previous discussion if you're aware of any?
Regardless:
# Form letter - net-next is closed
We have already sent the networking pull request for 5.16 and therefore net-next is closed for new drivers, features, code refactoring and optimizations. We are currently accepting bug fixes only.
Please repost when net-next reopens after 5.16-rc1 is cut.
Look out for the announcement on the mailing list or check: http://vger.kernel.org/~davem/net-next.html
RFC patches sent for review only are obviously welcome at any time.
