Issue found on J-gcp-6.5.0-1015.15~22.04.1 and M-gcp-6.5.0-1015.15 in cycle sru-20240205
And can be reproduced with generic kernel on GCP cloud.
This is not a regression but something emerges after the pmtu.sh result parsing logic update, which landed via stable update in sru-20240205 cycle (bug 2043198)
Dive into test history, we can see this failure all the way back to sru-20231030 with M-6.5.0-1010.10 on GCP cloud.
