    nFAPI/VNF: Correctly set message length when segmenting · 2067831e
    Robert Schmidt authored
    The 5G nFAPI message length is 32bits. In particular tx_data.requests
    can be longer than 64kB. When segmenting, we should correctly write the
    message of the current segment (across all 32bits), because the
    length would interpreted wrongly otherwise.
    
    This fixes a bug in which tx_data.requests were discarded for 4-layer DL
    MIMO on 100 MHz with this message:
    
        P7 unpack message length is greater than the message buffer
    
    Further, increase the type of various (segment-related) variables to 32
    bits. Currently, the maximum segment size is sxt to 65000 bytes (and in
    will likely remain, because the maximum UDP size is 65536);
    nevertheless, increase it in case we will ever go beyond this.

    65000")
