You can look in the config I sent.. but here is what
I have added to enable BBR and Rack to be built
*****
makeoptions WITH_EXTRA_TCP_STACKS=3D1
options TCPHPTS=09
options RATELIMIT
******
So you should
1) Apply the current patch in phabricator
2) edit your config and add the above three lines
3) go to the src dir and type
make buildkernel KERNCONF=3Dmyconf
That should build and get you a kernel that will include bbr and rack. =
You will
need to, after it boots up type
kldload tcp_bbr
or
kldload tcp_rack
To get the modules loaded
