Hi,
The Payload is the same between UDP/TCP/SCTP Transport Layer ? It is not
possible to make a unique function to dissect payload ?

Create a header field (hf) by type of payload
Example
Replace
+ case PINGREQUEST:
+ case PINGREPLY:
+ value = tvb_get_bits8(buffer,offset * 8, 8);
+ proto_tree_add_bytes_format(payload_tree, hf_knet_msg_payload,
buffer, offset, 1, NULL, "PingID: %d", value);
+ break;
+ case FLOWCONTROLREQUEST:
+ value = tvb_get_bits8(buffer,offset * 8 + 8, 8) << 8;
+ value += tvb_get_bits8(buffer,offset * 8, 8);
+ proto_tree_add_bytes_format(payload_tree, hf_knet_msg_payload,
buffer, offset, 3, NULL, "New Datagram Rate: %d", value);
+ break;
by
+ case PINGREQUEST:
+ case PINGREPLY:
+ proto_tree_add_item(payload_tree, hf_knet_msg_payload_pingid,
buffer, offset, ENC_BIG_ENDIAN);
+ break;
+ case FLOWCONTROLREQUEST:
+ proto_tree_add_item(payload_tree,
hf_knet_msg_payload_flowcontrolrequest, buffer, offset, ENC_BIG_ENDIAN);
+ break;
Also for proto_tree_add_item, use ENC_NA/ENC_LITTLE_ENDIAN/ENC_BIG_ENDIAN for
encoding attribut (and not TRUE / FALSE it is deprecated )
