3.15-stable review patch. If anyone has any objections, please let me know.
------------------ From: Or Gerlitz <[email protected]> commit 652c1a05171695d21b84dd3a723606b50eeb80fd upstream. In commit f360d88a2efd, we advertise blocking multicast loopback to both kernel and userspace consumers, but don't allow kernel consumers (e.g IPoIB) to use it with their UD QPs. Fix that.
