[ovs-dev] [PATCH 1/3] ovsdb-idl: Avoid sending redundant conditional monitoring updates

[Andy Zhou]

In case connection is reset when there are buffered but unsent
conditions, these conditions will be sent as the new "monitor_cond"
message that will be sent after the idl reconnects.

Without this patch, those conditions will be unnecessarily sent again
with following monitoring condition update message.
