  • Add callbacks and data types for statistics export of all current
    devices/ids. The schema for RDMA CM is a series of netlink messages.
    Each one contains an rdma_cm_stat struct. Additionally, two netlink
    attributes are created for the addresses for each message (if
    applicable).

    Their types used are:
    RDMA_NL_RDMA_CM_ATTR_SRC_ADDR (The source address for this ID)
    RDMA_NL_RDMA_CM_ATTR_DST_ADDR (The destination address for this ID)
    sockaddr_* structs are encapsulated within these attributes.

    In other words, every transaction contains a series of messages like:

    -------message 1-------
    struct rdma_cm_id_stats {
    __u32 qp_num;
    __u32 bound_dev_if;
    __u32 port_space;
    __s32 pid;
    __u8 cm_state;
    __u8 node_type;
    __u8 port_num;
    __u8 reserved;
    }
    RDMA_NL_RDMA_CM_ATTR_SRC_ADDR attribute - contains the source address
    RDMA_NL_RDMA_CM_ATTR_DST_ADDR attribute - contains the destination address
    -------end 1-------
    -------message 2-------
    struct rdma_cm_id_stats
    RDMA_NL_RDMA_CM_ATTR_SRC_ADDR attribute
    RDMA_NL_RDMA_CM_ATTR_DST_ADDR attribute
    -------end 2-------

  • Add basic RDMA netlink infrastructure that allows for registration of
    RDMA clients for which data is to be exported and supplies message
    construction callbacks.
