commit 534803d85ee9d3ad9a198fab72e94417dbe78047 Author: LIU Yulong <[email protected]> Date: Thu Aug 4 14:16:37 2016 +0800 Check the router gateway IPs prefixlen existence When we remove the router gateway, if it has multiple IPs for the gateway port, the router remove procedure will not work properly and will cause a router remove infinite loop. This is because the neutron server only gives the first (lowest) gateway IP a 'prefixlen', and not the secondary IPs, so the router remove will get a KeyError. This patch adds a `prefixlen` check before removing the gateway IPs conntrack state.
