+ Suppresses in-band control flows for the integration bridge. It would be
+ unusual for such flows to show up anyway, because OVN uses a local
+ controller (over a Unix domain socket) instead of a remote controller.
+ It's possible, however, for some other bridge in the same system to have
+ an in-band remote controller, and in that case this suppresses the flows
+ that in-band control would ordinarily set up. See <code>In-Band
+ Control</code> in <code>DESIGN.md</code> for more information.

The customary name for the integration bridge is <code>br-int</code>, but
another name may be used.
