7.3.2 Logical Layer Errors
SerB action includes sending an error response to either UL or RIO, an error response is only sent if the original transac-
tion was a request that required a response. Otherwise, no error response is sent. When dealing with multiple errors,
discard of packet has higher priority than error response.
