Does LE support BBR?

    I have noticed that LebriELEC is using cubic for congestion control which is not as good as bbr. However, I did't find a way to enable it as the files in /etc is not modifiable.

    # sysctl net.ipv4.tcp_available_congestion_control

    net.ipv4.tcp_available_congestion_control = reno cubic

    Anyone knows how to install BBR on LibreELEC?

    info about my system:

    hardware: Pi 4b

    kernel:

    # uname -r

    5.10.95

    BBR is not set in the 6.1 kernel either. To enable support and make an image for testing you will need to self-build an image.

    If you feel the distro defaults should be changed, you'll need to send a pull-request to our main GitHub repo with the required changes and a detailed explanation for why we need to change things. We're not adverse to changing defaults when there's a good reason, but you will need to impart and if necessary educate people on use-cases for/against and why the change is a good reason.
