| |
w/o RXE_START_MASK, the last_psn of IB_OPCODE_RC_SEND_ONLY_INV will not be updated in update_wqe_psn, and the corresponding wqe will not be acked in rxe_completer due to its last_psn is zero. Finally, the other wqe will also not be able to be acked, because the wqe of IB_OPCODE_RC_SEND_ONLY_INV with last_psn 0 is still there. This causes large amount of io timeout when nvmeof is over rxe.
Add RXE_START_MASK for IB_OPCODE_RC_SEND_ONLY_INV to fix this.
