Well, given N active bulk flows with packet size L, and assuming the
quantum Q=L (which is the default for FQ-CoDel at full-size 1500-byte
packets), the maximum rate for a sparse flow, R_s, is bounded by
R_s < R / ((L/L_s)(N+1))
Where R is the link rate and L_s is the packet size of the sparse flow.
This assumes that the sparse flow has constant spacing between its
packets, which is often the case for a VoIP flow...
