The optional and required hints in the tcp_congestion_ops are information
for the user of this interface to signalize its importance when
implementing these functions.
However, cong_avoid comment incorrectly tells that it is required,
in reality congestion control must provide one of either cong_avoid or
cong_control.
In addition, min_tso_segs has not had any comment optional/required
hints. So mark it as optional since it is used only in BBR.
