摘要： A network interface system includes a memory system for managing data obtained via a system bus that supports split transactions. The memory system comprises a first memory for storing outgoing assembled data frames and associated control information prior to transfer of the outgoing data to the network, and an assembly memory that stores unassembled outgoing data from the bus. A memory control system stores the control information associated with pending bus read requests and also transfers outgoing data from the assembly memory to the first memory when all the outgoing data for a corresponding read request has been assembled.

摘要： A network node has multiple physical layer devices (PHYs), multiple media access controllers (MACs), and means for gathering information regarding the capabilities of other nodes on the network. The node capability information may be gathered using hardware or software, and may involve gathering information from data frames received by the node, and/or from capability and status announcement frames received by the node. The node capability information gathered and the node topology determined may be utilized in selecting one of the MACs as an active MAC for monitoring a network medium, and/or in selecting one of the PHYs as an active PHY for transmission of frames onto the network medium. The PHYs of the interface in an exemplary embodiment are able to transmit and receive data frames or packets which are in accordance with different home phoneline networking alliance (HPNA) specifications, for example, HPNA 1.0 and HPNA 2.0.
