Comment 9 for bug 1639566

I reviewed [RFE]"Fast exit" and related master based patch: https://review.openstack.org/#/c/283757/.
'Fast exit' implementation uses very close concept to my own reference implementation. While I used agent gateway addresses based on API manual set, 'Fast exit RFE' uses advanced neutron support of separate ip address pools per service type and takes gateway address from a dedicated pool.

My patch is less 'baked' compared to 'Fast exit' so I feel that bringing fresh patch to master will produce less benefit than reviewing and contributing to more 'baked' solution that 'walks' the same way.
