docs: Send a junk packet across the encrypted link.  This is sometimes used
          to add "noise" to a connection to confuse would-be attackers.  It can
          also be used as a keep-alive for long lived connections traversing
          firewalls.
  
          :param int byte_count:
              the number of random bytes to send in the payload of the ignored
              packet -- defaults to a random number from 10 to 41.
