Attached is a small patch for packet-enip.c. It make is possible to
dissect EtherNet/IP packets that contains two or more messages
encapsulated into one packet.

Does that happen for ENIP-over-UDP, or just for ENIP-over-TCP?

This is something that only can happend on TCP.

OK, I've checked in a change to make the ENIP-over-TCP dissector use "tcp_dissect_pdus()"; there's a preference setting to control whether messages split across TCP segment boundaries should be reassembled (it's on by default, and is in the "Edit->Protocols" dialog box, under "ENIP"; you need to turn TCP reassembly on as well - that's in "Edit->Protocols", under TCP). Whether that preference is on or off, it should handle multiple messages in a single TCP segment.
