    Correct the usage of req's segment_first and segment_size in sendNonContig · 5132e070
    Xin Zhao authored and Pavan Balaji's avatar Pavan Balaji committed
    The implementations of sendNoncontig for intra-node communication in
    Nemesis and inter-node communication in network modules (except for
    TCP and SCIF) assume that req->dev.segment_first is zero and
    req->dev.segment_size is the size of data, which is not always true.
    If we stream an RMA operation and issue partial of derived data,
    req->dev.segment_first specifies the current starting location of the data
    and req->dev.segment_size specifies the current ending location of the data.
    Also, the data size should be (req->dev.segment_size - req->dev.segment_first).
    This patch corrects this issue in Nemesis and network modules.
