[Cake] cake vs fqcodel with 1 client, 4 servers

[Georgios Amanakis]

I tried to simulate a situation resembling Windows
updates/Steam/Torrents on a slow 10/2mbit connection.

veth setup, 1 client, 4 servers
setup.tgz:
./vsetup.sh
./sshd.sh
./vcake.sh
./mm.sh

servers   --   delay   --   isp   --   mbox   --   client
(4)	       20ms      10/2mbit    9/1.8mbit     (1)

The client is creating in parallel 11 downstream and 2 upstream flows
to *each* of the 4 servers.
This was done by running 4 rrul_be_nflows tests in parallel.

Cake vs HTB/fqcodel at mbox.
Cake tested with ack-filter and ingress/egress.

Cake ingress, as expected, achieves better latency at the cost of
bandwidth. This does wonders on slow connections like mine.

I will try to increase the number of clients to 4 and run some tests.
