IPoIB: Only set Q_Key once: after joining broadcast group
The current code will set the Q_Key for any join of a non-sendonly multicast group. The operation involves a modify QP operation, which is fairly heavyweight, and is only really required after the join of the broadcast group. Fix this by adding a parameter to ipoib_mcast_attach() to control when the Q_Key is set. Signed-off-by: Eli Cohen <eli@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
