dot3ExtPkgQueueTable

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 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. 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 which is not a bridge, with embedded 
bridging queues. The format of the REPORT message, 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 ExtPkgQueueSetsTable 
table. For each set the report bitmap defines which queue is 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 Queue table has a variable size which is limited by the 
ExtPkgObjectReportMaximumNumQueues 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 which 
are gathered in an extended package as an addition to the objects which 
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 2bytes register (15bits 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 
ExtPkgObjectReportMaximumNumQueues.
