Commit Message

Han Zhou May 28, 2021, 7:23 p.m. UTC 
Always monitor all logical datapath groups. Otherwise, DPG updates may
be received *after* the lflows using it are seen by ovn-controller.
Since the number of DPGs are relatively small, we monitor all DPGs to
avoid the unnecessarily extra control plane round trip for the lflows to
be processed.
