When we receive a netdev event indicating a netdev change and/or a netdev address change, we must change the MAC index used by the proxy QP1 (in the QP context), otherwise RoCE CM packets sent by the VF will not carry the same source MAC address as the non-CM packets. We use the UPDATE_QP command to perform this change. In order to avoid modifying a QP context based on netdev event, while the driver attempts to destroy this QP (e.g either the mlx4_ib or ib_mad modules are unloaded), we use mutex locking in both flows. Since the relevant mlx4 proxy GSI QP is created indirectly by the mad module when they create their GSI QP, the mlx4 didn't need to keep track on that QP prior to this change. Now, when QP modifications are needed to this QP from within the driver, we added refernece to it.
