ovsdb-server now accepts "monitor_cond_change" request. After conditions change we compose update notification according to the current state of the database without using a change list before sending reply to the monitor_cond_change request. Sees ovsdb-server (1) man page for details of monitor_cond_change. Signed-off-by: Liran Schour <lirans@il.ibm.com> Signed-off-by: Ben Pfaff <blp@ovn.org>
