      DESCRIPTION
              "A table of the extended package objects for queue
               management.  The [802.3ah] MPCP defines a report message
               of the occupancy of the transmit queues for the feedback

               transmission of the ONU and data is gathered there until
               the ONU is granted for transmission.
               The management table of the queues is added here mainly
               to control the reporting and to gather some statistics
               of their operation.  This table is not duplicating
               existing management objects of bridging queues,
               specified in [802.1d], since the existence of a
               dedicated transmit queuing mechanism is implied in the
               [802.3ah], and the ONU may be a device that is not a
               bridge with embedded bridging queues.
               The format of the REPORT message, as specified

               The 'Queue report' field reports the occupancy of each
               uplink transmission queue.
               The number of queue sets defines the number of the
               reported sets, as would be explained in the description
               of the dot3ExtPkgQueueSetsTable table.  For each set the
               report bitmap defines which queue is present in the
               report, meaning that although the MPCP REPORT message
               can report up to 8 queues in a REPORT message, the
               actual number is flexible.  The Queue table has a
               variable size that is limited by the
               dot3ExtPkgObjectReportMaximumNumQueues object, as an
               ONU can have fewer queues to report.
               The entries in the table are control and status
               indication objects for managing the queues of an EPON
               interface that are gathered in an extended package as
               an addition to the objects that are based on the
               [802.3ah] attributes.
               Each object has a row for every virtual link and for
               every queue in the report.
               The LLID field, as defined in the [802.3ah], is a 2-byte
               register (15-bit field and a broadcast bit) limiting the
Top   ToC   RFC4837 - Page 67
               number of virtual links to 32768.  Typically the number
               of expected virtual links in a PON is like the number of
               ONUs, which is 32-64, plus an additional entry for
               broadcast LLID (with a value of 0xffff).
               The number of queues is between 0 and 7 and limited by

              "A table of Extended package objects used for the
               management of the queue_sets.  Entries are control and
               status indication objects of an EPON interface, which
               are gathered in an extended package as an addition to
               the objects based on the [802.3ah] attributes.  The
               objects in this table are specific for the queue_sets,
               which are reported in the MPCP REPORT message as defined
               in [802.3ah], clause 64.
               The [802.3ah] MPCP defines a report message of the
               occupancy of the transmit queues for the feedback BW
               request from the ONUs.  These queues serve the uplink
               transmission of the ONU and data is gathered there until
               the ONU is granted for transmission.
Top   ToC   RFC4837 - Page 71
               The management table of the queues_sets is added here
               mainly to control the reporting and to gather some
               statistics of their operation.  This table is not
               duplicating existing management objects of bridging
               queues, specified in [802.1d], since the existence of a
               dedicated transmit queuing mechanism is implied in the
               [802.3ah], and the ONU may be a device that is not a
               bridge with embedded bridging queues.
               The format of the REPORT message, as specified
               in [802.3], is presented below:

               As can be seen from the message format, the ONU
               interface reports of the status of up to 8 queues
Top   ToC   RFC4837 - Page 72
               and it can report in a single MPCP REPORT message
               of a few sets of queues.
               The number of queue_sets defines the number of the
               reported sets, and it can reach a value of up to 8.
               It means that an ONU can hold a variable number of
               sets between 0 and 7.
               The dot3ExtPkgQueueSetsTable table has a variable
               queue_set size that is limited by the
               dot3ExtPkgObjectReportMaximumNumThreshold object as an
               ONU can have fewer queue_sets to report.
               The 'Queue report' field reports the occupancy of each
               uplink transmission queue.  The queue_sets can be used to
               report the occupancy of the queues in a few levels as to
               allow granting, in an accurate manner, of only part of
               the data available in the queues.  A Threshold is
               defined for each queue_set to define the level of the
               queue that is counted for the report of the occupancy.
               The threshold is reflected in the queue_set table by the
               dot3ExtPkgObjectReportThreshold object.
               For each queue set, the report bitmap defines which
               queues are present in the report, meaning that
               although the MPCP REPORT message can report of up to 8
               queues in a REPORT message, the actual number is
               flexible.
               The dot3ExtPkgQueueSetsTable table has a variable queue
               size that is limited by the
               dot3ExtPkgObjectReportMaximumNumQueues object as an ONU
               can have fewer queues to report.
               Each object has a row for every virtual link, for each
               queue in the report and for each queue_set in the queue.
               The LLID field, as defined in the [802.3ah], is a 2-byte
               register (15-bit field and a broadcast bit) limiting the
               number of virtual links to 32768.  Typically the number
               of expected virtual links in a PON is like the number of
               ONUs, which is 32-64, plus an additional entry for
               broadcast LLID (with a value of 0xffff).
               The number of queues is between 0 and 7 and limited by
               dot3ExtPkgObjectReportMaximumNumQueues.
               The number of queues_sets is between 0 and 7 and limited
               by dot3ExtPkgObjectReportMaximumNumThreshold."
