    IB/core: generic RDMA READ/WRITE API · a060b562
    Christoph Hellwig authored
    This supports both manual mapping of lots of SGEs, as well as using MRs
    from the QP's MR pool, for iWarp or other cases where it's more optimal.
    For now, MRs are only used for iWARP transports.  The user of the RDMA-RW
    API must allocate the QP MR pool as well as size the SQ accordingly.
    
    Thanks to Steve Wise for testing, fixing and rewriting the iWarp support,
    and to Sagi Grimberg for ideas, reviews and fixes.
