DESCRIPTION
    A mixin class for basic interface related infos from the ifTable and
    ifXTable.

    This mixin supports the quasi static information from both tables
    together in one hash, see below.

MIXIN METHODS
  OBJ->get_if_entries
    Returns parts ot the ifTable and ifXTable as a hash reference. The key
    is the common ifIndex into the ifTable and ifXtable:

      {
        INTEGER => {    # ifIndex as key

          ifName      => DisplayString,    # ifXTable entries
          ifAlias     => DisplayString,
          ifHighspeed => GAUGE,

          ifDescr       => DisplayString,    # ifTable entries
          ifType        => IANAifType,
          ifMtu         => INTEGER,
          ifSpeed       => GAUGE,
          ifPhysAddress => PhysAddress,
          ifAdminStatus => INTEGER,
          ifOperStatus  => INTEGER,
          }

          ...,
      }

INITIALIZATION
  OBJ->_init($reload)
    Fetch basic interface related snmp values from the host. Don't call this
    method direct!

PRIVATE METHODS
    Only for developers or maintainers.

  _fetch_if_entries($session)
    Get selected MIB values from the ifTable and ifXTable.

  _if_entries_cb($session)
    The callback for _fetch_if_entries

    dot1dBasePorts.
