Describe the bug
When configuring qdisc-bypass: false and a downstream-only stream, BNG-Blaster shows rx-packets on the network-interface, although no rx-packets are received:
qdisc-bypass: false
This wrongly counted rx-packets are included in the report, too:

When setting qdisc-bypass: true the rx-packets are not counted:
qdisc-bypass: true
To Reproduce Use the PPPoE Quick-Start guide and disable qdisc-bypass.

Steps to reproduce the behavior:
Additional context
We want to bypass qdisc in egress to apply tc netem rules for simulating network issues like packet loss, latency etc.
