To clarify the intent of this change: The RDMA CM allows users to specify addresses using struct sockaddr. Today, only INET/6 are supported. The intent is to allow a user to specify native InfiniBand addresses through that interface. In the more immediate, this helps to solve InfiniBand scaling issues. Longer term, this can also be used to control path failover. - Sean -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html ^ permalink raw reply [flat|nested] 6+ messages in thread
