So that we can write enip.revision: 0x203 Ticket: 6645
Ticket: 6647 Allows keywords using integers to use strings in signature parsing based on a rust enumeration with a derive.
Ticket: 6648 Like &0x40=0x40 to test for a specific bit set
Ticket: 6628 Document the generic detection capabilities for integer keywords. and make every integer keyword pointing to this section.
if no config option is found, as is done for udp Ticket: 6304
Including the one for websocket over HTTP/2
port is used in AppLayerProtoDetectProbingParserPort and not in AppLayerProtoDetectProbingParserElement
As for WebSocket which is detected only by protocol change.
When there is a protocol change, and a specific protocol is expected, like WebSeocket, always run it, no matter the port.

#10130 with code review taken into account for logging payload
I think this is good enough for a first version even if there may be improvements (that should happen in later tickets) :
This is a big one as websockets over HTTP/2 only use a single HTTP/2 stream and not the whole TCP connection which keeps having newer regular HTTP/2 streams (or other websocket ones). That means a HTTP2 transactions will own a Websocket State + some streaming buffer as TCP...
#9870 should likely precede this
