Need WG Consensus on VACM Extension

• docsDevVacmAccessIfIndex OBJECT-TYPE
• SYNTAX InterfaceIndexOrZero
• MAX-ACCESS read-create
• STATUS current
• DESCRIPTION
• The entry interface to which this filter
  applies. The value corresponds to ifIndex for
  either a CATV MAC or another network interface.
  If the value is zero, the filter applies to all
  interfaces. In Cable Modems, the default value is
  the customer side interface(s). In Cable Modem
  Termination Systems, this object has to be
  specified to create a row in this table. Note
  that according to the DOCSIS OSSIv1.1
  specification OSSI1.1, ifIndex '1' means that
  this row applies to all CPE (customer-facing)
  interfaces.
