* Configuration
*
* All configuration management messaging involves sending a request message
* to the TIPC configuration service on a node, which sends a reply message
* back. (In the future multi-message replies may be supported.)
*
* Both request and reply messages consist of a transport header and payload.
* The transport header contains info about the desired operation;
* the payload consists of zero or more type/length/value (TLV) items
* which specify parameters or results for the operation.
*
* For many operations, the request and reply messages have a fixed number
* of TLVs (usually zero or one); however, some reply messages may return
* a variable number of TLVs. A failed request is denoted by the presence
* of an "error string" TLV in the reply message instead of the TLV(s) the
