[ovs-discuss] Overlapping rules with identical actions

Hi All,

If the OFPFF_CHECK_OVERLAP flag is not set and a Controller (erroneously)
sends an Openflow rule that has *both* identical match conditions &
identical actions to that of an existing rule how would OVS handle this?
Would the new rule still overwrite the old rule or is there an inexpensive
way of determining this case, rejecting the new rule and notifying an error
to the Controller?
