Another new feature, highly experimental, just went in. Cake will now = dynamically estimate the capacity of its input traffic, and report that = through tc. The capacity estimate can be significantly higher than the = shaped rate, because it examines the input timings, not the output. = Note that it doesn=E2=80=99t yet account for packet overhead. I anticipate it may be useful for tuning ingress shaping. In future, it = may be possible to automatically set the shaping rate in such = configurations - particularly useful for cases where the capacity is = variable on a diurnal and/or coverage basis. Now, let=E2=80=99s see what I can do about dual isolation... - Jonathan Morton
