SIP and SSDP share method names like NOTIFY and SUBSCRIBE,
causing SSDP traffic to be misidentified as SIP.
Add a probing parser callback that checks for "SIP/" in the
payload before accepting a pattern match.
Example of a misidentified flow before the fix:
{"timestamp":"2014-02-27T19:44:43.164211+0100","flow_id":986757542077835,"event_type":"flow","src_ip":"192.168.1.1","src_port":9489,"dest_ip":"239.255.255.250
","dest_port":1900,"ip_v":4,"proto":"UDP","app_proto":"sip","flow":{"..."}}
After the fix:
{"timestamp":"2014-02-27T19:44:43.164211+0100","flow_id":986757542077835,"event_type":"flow","src_ip":"192.168.1.1","src_port":9489,"dest_ip":"239.255.255.250
","dest_port":1900,"ip_v":4,"proto":"UDP","app_proto":"failed","flow":{"..."}}
Ticket OISF#8355
It's no longer useful to set an event when the data is incomplete, since an error is returned. Ticket OISF#8524
