> Currently, floating buffers (per gate) are always required in case credit-based flow
control is enabled. This, however, increases our minimum number of required network buffers.
> Instead, without changing too much, we could already work with a minimum of one or zero
floating buffers and set the max to the configured value. This way, if there are not enough
buffers, allĀ {{LocalBufferPool}}s will at least share the available ones.
