The method that is used to determine which congestion control mechanism is
determined by the setting of the sysctl net.ipv4.tcp_congestion_control.
The default congestion control will be the last one registered (LIFO);
so if you built everything as modules. the default will be reno. If you
build with the default's from Kconfig, then BIC will be builtin (not a module)
and it will end up the default.
so if you built everything as modules, the default will be reno. If you
build with the defaults from Kconfig, then CUBIC will be builtin (not a
module) and it will end up the default.
If you really want a particular default value then you will need
to set it with the sysctl. If you use a sysctl, the module will be autoloaded
