These functions had no callers, so remove them and the data maintained just to implement them. Found by inspection. Signed-off-by: Ben Pfaff <blp@nicira.com> Acked-by: Thomas Graf <tgraf@noironetworks.com>

/* A wrapper around vconn that provides queuing and optionally reliability.
|
|
*
|
|
* An rconn maintains a message transmission queue of bounded length specified
|
|
* by the caller. The rconn does not guarantee reliable delivery of
|
|
* queued messages: all queued messages are dropped when reconnection becomes
|
|
* necessary.
|
|
*
|
|
* An rconn optionally provides reliable communication, in this sense: the
|
|
* rconn will re-connect, with exponential backoff, when the underlying vconn
|
|
* disconnects.
|
|
*
|
|
*
|
|
* Thread-safety
|
|
* =============
|
|
*
|
|
* Fully thread-safe.
