IB/core: Reset to error QP state transition is not allowed
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. Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
