From e82bb7ea72d7d457ec861f44a1a47f07b7a51baa Mon Sep 17 00:00:00 2001 From: Or Gerlitz Date: Wed, 25 Jun 2014 16:44:14 +0300 Subject: [PATCH] IB/mlx5: Enable "block multicast loopback" for kernel consumers 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.
