I was able to apply the patch - now rebuilding the kernel. Would update on how it goes. BTW, is there any description on how lack of tc_fq under FreeBSD is compensated here? The original BBR patches on Linux show that as a must-have? Is that functionality implemented via tcp_ratelimit.[ch]? Any pointers to existing presentations/discussions highly appreciated? Thanks a lot. On Tue, Sep 17, 2019 at 5:39 AM Randall Stewart wrote: > You should be able to compile it against the current head.
