The help text for configuring  TCP_CONG_BBR  states:

--- Quote ---It requires the fq ("Fair Queue") pacing packet scheduler.
--- End quote ---

I don't see anything in the Kconfig file that enables that when  TCP_CONG_BBR  is selected. You should check that:

--- Code: ---NET_SCH_FQ
--- End code ---
is enabled prior to compiling.

Thanks, I will try it later.

Tiny core 15 x86 still does not have BBR, but picore 15 does . Is there a wishlist thread for tiny core 16? I would like to have both Pi and x86 kernels bullt with same features.
