If you want to delete all of the outstanding WRs, you should move the QP
state to reset.
(Is this is what you asked?)
My question was more along the lines - can I expect that all pending
WRs have been flushed when ib_modify_qp returns? At least for error
state this does not seem to be the case - I'm still getting completions
on the receive QP from the mellanox card after I do this.
I couldn't find in the IB spec any mention on this (that moving a QP to
error means that all of the outstanding
completions are already flushed and can be found in the CQ when the
modify_qp command returns).
I think that this is not guaranteed and you can't count on it on any IB
HCA (even in none Mellanox HCAs).
