Actually I recall adding "current QP state" as an input modifier
to the modify QP verb as part of the IB 1.1 errata (if I remember
correctly). The main intention is to avoid the ambiguity when
a consumer moves a QP into RTS state but can't tell if the QP
was in SQError/Error or SQDrain. According to the spec, current
QP state should only be valid when moving QP into RTS state.
Hope that helps.
