the host to host controller flow control means that we tell the chip to
use flow control. This is the other way around and we don't support it
at the moment, because it is easy for us to handle big packets. If you
enable host to host controller flow control you need to tell the chip
when you are ready to receive more packets.
Regards
Marcel
