OpenFlow works with many different kinds of messages, so it can be helpful
to state that specifically *log* messages were dropped. Thanks to Pete
for pointing this out (see bug #1166).
if (rl->n_dropped) {
vlog(module, level,
- "Dropped %u messages in last %u seconds due to excessive rate",
+ "Dropped %u log messages in last %u seconds "
+ "due to excessive rate",
rl->n_dropped, (unsigned int) (time_now() - rl->first_dropped));
rl->n_dropped = 0;
}
