[ofa-general] Re: [PATCH 2/3] mcast loopback block

[Roland Dreier]

actually, looking at this further:

> +int mlx4_multicast_attach(struct mlx4_dev *dev, struct mlx4_qp *qp, u8 gid[16], int block_mcast_lb)

given that the real change is to multicast attach and is not a property
of QPs, wouldn't it be simpler to simply add a flags argument to
ib_attach_mcast() and use a flag bit to request that messages not be
looped back per mcast attach?
