The commit being fixed introduced the different format for the transmitting descriptor multi-packet session for ConnectX-4LX. The session was assumed always opened if not-inlinable packet was encountered. The patch checks whether the inline multi-packet is opened and it allows to proceed with normal packets (non inlined) successfully.
