From b45b68ae4ab90af1ce35deec52b0c0492a1f49d4 Mon Sep 17 00:00:00 2001 From: Martin Sustrik Date: Wed, 23 Mar 2011 17:01:39 +0100 Subject: ZMQ_MCAST_LOOP removed Multicast loopback is not a real multicast, rather a kernel-space simulation. Moreover, it tends to be rather unreliable and lossy. Removing the option will force users to use transports better suited for the job, such as inproc or ipc.
