Added macros for min/default/max link priority in tipc_config.h. Also renamed TIPC_NUM_LINK_PRI to TIPC_MEDIA_LINK_PRI since that is a more accurate description of what it is used for. Signed-off-by: Per Liden <per.liden@ericsson.com>

* 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
|
|
* reply should contain if the request succeeds.
