IB/core: Add support for multicast loopback blocking
This patch also adds a creation flag for QPs, IB_QP_CREATE_MULTICAST_BLOCK_LOOPBACK, which when set means that multicast sends from the QP to a group that the QP is attached to will not be looped back to the QP's receive queue. This can be used to save receive resources when a consumer does not want a local copy of multicast traffic; for example IPoIB must waste CPU time throwing away such local copies of multicast traffic. This patch also adds a device capability flag that shows whether a device supports this feature or not. Signed-off-by: Ron Livne <ronli@voltaire.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
