Running on 32-bit Windows 7 Service Pack 1, build 7601, with WinPcap version
4.1.3 (packet.dll version 4.1.0.2980), based on libpcap version 1.0 branch

Steps to reproduce:
1) Start a capture on an interface that an OPCUA server is listening on
2) Establish a connection to the OPCUA server from an OPCUA client and read
values of a node
3) The OPCUA conversation is shown in wireshark as TCP protocol
4) Enter "opcua" in the filter box to show packets containing the OPCUA
conversation - none are shown
It seems that Wireshark is not identifying a conversation as OPCUA. A similar
conversation has been observed using the "opcua" filter in previous versions of
Wireshark.
A capture of the OPCUA conversation is attached.
