This is a completely separate TCP stack (tcp_bbr.ko) that will be built only if you add the make options WITH_EXTRA_TCP_STACKS=1 and also include the option TCPHPTS. You can also include the RATELIMIT option if you have a NIC interface that supports hardware pacing, BBR understands how to use such a feature. So i think you need te rebuild with the following option set WITH_EXTRA_TCP_STACKS=1 regards Johan HendriksReceived on Fri Apr 24 2020 - 11:46:27 UTC
