The kernel module is built: $ modinfo tcp_bbr filename: /lib/modules/5.6.0-0.rc5.git0.2.fc32.x86_64/kernel/net/ipv4/tcp_bbr.ko.xz description: TCP BBR (Bottleneck Bandwidth and RTT) > root@kuriiti network-scripts]# sysctl > net.ipv4.tcp_available_congestion_control > net.ipv4.tcp_available_congestion_control = reno cubic If you manually load the module it's there: # sysctl -a | grep tcp_available_congestion_control net.ipv4.tcp_available_congestion_control = reno cubic # modprobe tcp_bbr # sysctl -a | grep tcp_available_congestion_control net.ipv4.tcp_available_congestion_control = reno cubic bbr I'm not sure the "official" way to use different congestion control algorithms but I'm guessing it's something you can use NetworkManager to specify and autoload them.
