[Bug 1622783] [NEW] unnecessary DHCP provisioning block added when IP doesn't change

 

Public bug reported:

Right now we insert a DHCP provisioning block on any port update.
However, this isn't necessary if the IP address of the port hasn't
actually changed. This can be problematic particularly if a port is
updated via the internal core plugin API and the DHCP agent doesn't get
notified of the change so the block doesn't get cleared.
