Bug Description

in neutron/ _update_fip_assoc is executed from within a database transaction.

The same routine for the nvp plugin executes backend operations such as updating the nat rules and ip addresses on the nvp platform, thus potentially triggering the deadlock with another mysql transaction such as the state report from an agent or a concurrent request.
