 * 5.1.  Treatment-Action AVP

   The Treatment-Action AVP (AVP Code 572) is of type Enumerated and
   lists the actions that are associated with the condition part of a
   rule.  The following actions are defined in this document:

      0: drop
      1: shape
      2: mark
      3: permit

   drop:

      This action indicates that the respective traffic MUST be dropped.

   shape:

      [RFC2475] describes shaping as "the process of delaying packets
      within a traffic stream to cause it to conform to some defined
      traffic profile".  When the action is set to 'shape', the QoS-
      Parameters AVP SHALL contain QoS information AVPs, such as the
      TMOD-1 and Bandwidth AVPs [RFC5624], that indicate how to shape
      the traffic described by the condition part of the rule.
      
   mark:

      [RFC2475] describes marking as "the process of setting the DS
      codepoint in a packet based on defined rules".  When the action is
      set to 'mark', the QoS-Parameters AVP SHALL contain QoS
      information AVPs, such as the PHB-Class AVP [RFC5624], that
      indicate the Diffserv marking to be applied to the traffic
      described by the condition part of the rule.

   permit:

      The 'permit' action is the counterpart to the 'drop' action used
      to allow traffic that matches the condition part of a rule to
      bypass.

   [RFC2475] also describes an action called 'policing' as "the process
   of discarding packets (by a dropper) within a traffic stream in
   accordance with the state of a corresponding meter enforcing a
   traffic profile".  This behavior is modeled in the Filter-Rule
   through the inclusion of the Excess-Treatment AVP containing a
   Treatment-Action AVP set to 'drop'.

   Further action values can be registered, as described in
   Section 10.3.
