# "ovs-ofctl" interface.
# For "ovs-ofctl" interface, "deferred" mechanism would improve
# performance by batching flow-mods with a single ovs-ofctl command
# invocation.
# On the other hand, for this "native" interface, the overheads of
# each flow-mods are already minimum and batching doesn't make much
# sense. Thus this method is left as no-op.
# It might be possible to send multiple flow-mods with a single
# barrier. But it's unclear that level of performance optimization
# is desirable while it would certainly complicate error handling.
