    IB/core: Reset to error QP state transition is not allowed · e5a5e7d5
    Ralph Campbell authored
    I was reviewing the QP state transition diagram in the IB 1.2.1 spec
    and the code for qp_state_table[], and noticed that the code allows a
    QP to be modified from IB_QPS_RESET to IB_QPS_ERR whereas the notes
    for figure 124 (pg 457) specifically says that this transition isn't
    allowed.  This is a clarification from earlier versions of the IB
    spec, which were ambiguous in this area and suggested that the RESET
    to ERR transition was allowed.
    
    Fix up the qp_state_table[] to make RESET->ERR not allowed.
