[Openib-windows] post send request in invalid QP state

[Yossi Leybovich]

Fab
 
In the documentation of IBAL its states , that if one post WQ to QP that
is not in valid state (RTR)  it should get IB_INVALID_QP_STATE.
If you want to check qp state you need to issue query_qp and still you
have race with the wire ( like RTR that move to RTS or RTS that move to
ERR)
The only state that may generate this error is RESET which is not
creating CQE, all other state return CQE with error so let the user
check the CQE.
 
Our new implementation of mthca skip the QP state checkin ( like gen2)
and relay on the CQE.
Can we change the documentation of the verb and remove this return value
? or state that its for RESET state?
 
Thanks
Yossi
