Subject: IB/mlx5: Enable "block multicast loopback" for kernel consumers
From: Or Gerlitz <ogerlitz@xxxxxxxxxxxx>
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.
Fixes: f360d88a2efd ("IB/mlx5: Add block multicast loopback support")
