Hi Michael, thanks for your reply. I tried tcp_rack and tcp_bbr, since both are separate TCP stacks. I just = posted the wrong error message. Both TCP stacks weren=E2=80=99t loadable = as a kernel module with just the former mentioned build option. I currently have build running with both kernel options you mentioned. If the build is successful and I can change the default TCP stack to = RACK and BBR I let you know. Further I didn=E2=80=99t find any documentation within tcp(4) regarding = RACK and BBR. Since I am about to enhance the manpages, I=E2=80=99ll = extent tcp(4) about information about RACK and BBR, but this is a = different topic.
