[ Upstream commit 5f2c7ab15fd806043db1a7d54b5ec36be0bd93b1 ]
The test assumes that the packet it is sending is the only packet being
passed to the device.
However, it is not the case and so other packets are filling the buffers
as well. Therefore, the test sometimes fails because it is reading a
maximum occupancy that is larger than expected.
Add egress filters on $h1 and $h2 that will guarantee the above.

[ Upstream commit cf3515c556907b4da290967a2a6cbbd9ee0ee723 ]
The test is sending only one packet generated with mausezahn from $h1 to
$h2. However, for some reason, it is testing for non-zero maximum occupancy
in both the ingress pool of $h1 and $h2. The former only passes when $h2
happens to send a packet.
Avoid intermittent failures by removing unintentional test case
regarding the ingress pool of $h1.
