[ofw] IB Atomic COMPARE_AND_SWAP returns IB_AE_WQ_REQ_ERR?

[Yossi Leybovich]

what HW do you use? 
 
if its mellanox HW there should be vendor syndrome in the EQE entry , it should be in the same offset of the vendor syndrome of the CQE.
You can change the driver to report it - this will might help us to identify the problem

Hello all,
  I'm working on DAT v2 extensions which include an Atomic
Compare-n-swap operation.
The comp-n-swap operation generates an async QP error callback with
IB_AE_WR_REQ_ERR?
The IB_AE_WR_REQ_ERR code is defined as 'an Opcode violation @ the
responder'?

Any clues as to what might generate an IB_AE_WR_REQ_ERR or what an
opcode violation @ responder implies?

Anyone have an IBAL based compare-n-swap test program they would like to
share?

Thanks,

Stan.
