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’t 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’s see what I can do about dual isolation...
