    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.
