1. Use new enginefacade + l3_db breakage Use reader and writer for db operations. Partially-Implements blueprint: enginefacade-switch 2. Fix the callback pass for _prevent_l3_port_delete_callback which was changed in commit Ia8ac4f510c003667cac95f76dea0e9ae55159878 3. QoS driver integration Commit I5f747635be3fd66b70326d9f94c85a6736286bd2 removes the qos notification driver. Fixing the nsx-v and nsx-v3 to work only with the regular driver 4. _get_extra_routes_dict_by_router_id was removed by Ia815d6c597730bd5cb49455e7409ca747a4cc22c 5. Floating IP association without subnet gateway IP not supported by our plugins. Added in commit If212c36d918ed57400a53f4b5fa1925b3d1fa6fd Co-Authored-by: Adit Sarfaty <asarfaty@vmware.com> Change-Id: I277ec5c38c5895337011019f71d586b254bfafde
