     85 * [wiki:Software/Firmware/Framework/R3_arch/ip IPv4]
     86 * [wiki:Software/Firmware/Framework/R3_arch/udp UDP]
     87 * [wiki:Software/Firmware/Framework/R3_arch/tcp TCP]

    86 [wiki:Internal/SDR/Firmware/Framework/R3_arch/eth_from_host Host -> HW] : two types of Ethernet frames e.g. rmap and data frames.[[BR]]
    87 [wiki:Internal/SDR/Firmware/Framework/R3_arch/eth_to_host HW -> Host] : two types of Ethernet frames e.g. rmap read and data. The data frames are further classified in additional subtypes such as generic data, FFT data structures and so forth. Host may perform additional processing on the data structures.

    89 Segmentation - this function is performed by the 'Tx Ethernet Interface' module. This module will automatically segment the data structure if size is greater than 1500 bytes (payload is stored in Rx Buffer). Some control information are appended to denote first, intermediate and last segment. Refer to [wiki:Internal/SDR/Firmware/Framework/R3_arch/eth_to_host HW -> Host] for further details.
