Aaarg, hitting the same issue I digged logs and devstack gate script shell, came to the conclusion that neutron fullstack jobs should have solved this issue (since n8g-bagpipe fullstack gate hook was stolen from neutron's), ran a git blame on neutron's gate_hook.sh and ended up here, and found a mention on n8g-bagpipe failure in the bug description.
An "affected project: networking-bagpipe" would have spared me quite some time...
I just added n8g-bapipe and group-based-policy as affected projects.

But, well at least the solution is ready!
