 /**
  * Update a switches ports using SNMP polling
  *
  * There is an optional ``$results`` array which can be passed by reference. If
  * so, it will be indexed by the SNMP port index (or a decresing nagative index
  * beginning -1 if the port only exists in the database). The contents of this
  * associative array is:
  *
  *     "port"   => \Entities\SwitchPort object
  *     "bullet" =>
  *         - false for existing ports
  *         - "new" for newly found ports
  *         - "db" for ports that exist in the database only
  *
  * **Note:** It is assumed that the Doctrine2 Entity Manager is available in the
  * Zend registry as ``d2em`` in this function.
  *
  * @throws \OSS_SNMP\Exception
  *
  * @param \OSS_SNMP\SNMP $host An instance of \OSS_SNMP\SNMP for this switch
  * @param \OSS_Logger $logger An instance of the logger or false
  * @param array Call by reference to an array in which to store results as outlined above
  * @return \Entities\Switcher For fluent interfaces
