wow. You nailed it. Thank you for identifying the root cause. I'll open a call
with German Telekom to fix there ppp endpoint.

(x1) [~/pcaps] tshark -nr eth1.pcap -T fields -e 'pppoe.session_id' | sort -u

0x0000b53b
0x0000b5e0
0x0000b7b3

These are exactly the packages I was missing:

(x1) [~/pcaps] tshark -nr eth1.pcap -Y 'pppoe.session_id = 0x0000b5e0'
