Ok, maybe I was not clear enough.
This bug is not related to bug 5622. Bug 5622 would allow to see the packet
which is over IP.
My patch does not intent to call CLNP dissector over IP if IP ptro field is
0x50. My patch corrects a specific CLNP Option Section.
To see the CLNP packet, you need to add the dissector clnp to your IP dissector
table for entry 0x50. Personally I do that using LUA scripting
clnp_dissector = Dissector.get("clnp")
local ip_table = DissectorTable.get("ip.proto")
ip_table:add(80, clnp_dissector)
On the first packet, the CLNP PDU starts at 0x22 "0x81a401649e..."
On the 2nd packet, the CLNP PDU starts at 0x22 "0x81a401619e..."
I hope that makes more sense now.
