[ofa-general] [PATCH 4/4] libibverbs: Add new creation flag: IBV_QP_CREATE_MULTICAST_LOOPBACK_BLOCK

[Ron Livne]

Adds enum ibv_qp_create_flags, which holds all possible
user-space creation flags for a QP.
This enum currently has one flag: IBV_QP_CREATE_MULTICAST_LOOPBACK_BLOCK
Which will be used for creating a UD QP that blocks multicast loopback packets.
This will only work if the device has this capability - currently only for mlx4
