From: Shalom Lagziel <shaloml@xxxxxxxxxxxx> In IPoIB connected mode the WQE opcode can be IB_WR_SEND only (stateless offloads are supported only in datagram mode), but it wasn't initialized. It leads to unpredictable CQE errors which were triggered by ipoib_cm_send() flow. In order to fix it, we initialize the wqe opcode in the set mode function to be IB_WR_SEND.
