The current number of connections that are in the backlog.
This gauge includes connections in ESTABLISHED or
SYN-RECEIVED states for which the Listener has not yet
issued an accept.
If this listener is using some technique to implicitly
represent the SYN-RECEIVED states (e.g., by
cryptographically encoding the state information in the
initial sequence number, ISS), it MAY elect to exclude
connections in the SYN-RECEIVED state from the backlog.
