+++ This bug was initially created as a clone of Bug #2128697 +++

The ML2/OVS mechanism driver is deprecated in RHOSP 17.1.

Over several releases, Red Hat is replacing ML2/OVS with ML2/OVN.
Support will be available for the deprecated ML2/OVS mechanism driver through the RHOSP 17.0 and 17.1 releases. During this time, ML2/OVS driver is in maintenance mode, getting bugfixes and normal support, and most new feature development will only happen in the ML2/OVN mechanism driver.
In RHOSP 18.0, Red Hat plans to completely remove the ML2/OVS mechanism driver and stop supporting it.

This is the 17.1 bug to track this deprecation, proper removal is tracked in OSP 18 bug #2100403
