+Subject: [PATCH 3/3] WPS UPnP: Handle HTTP initiation failures for events more
+ properly
+
+While it is appropriate to try to retransmit the event to another
+callback URL on a failure to initiate the HTTP client connection, there
+is no point in trying the exact same operation multiple times in a row.
+Replve the event_retry() calls with event_addr_failure() for these cases
+to avoid busy loops trying to repeat the same failing operation.
+
+These potential busy loops would go through eloop callbacks, so the
+process is not completely stuck on handling them, but unnecessary CPU
+would be used to process the continues retries that will keep failing
+for the same reason.
