When using TIPC_SOCK_RECVQ_DEPTH for getsockopt(), it returns the number of buffer elements in receive socket buffer which is not so helpful for user applications.
By returning the current number of allocated bytes of the receive socket buffer, applications can dimension its buffer usage to avoid buffer overload issue.
