Object

column mandatory r/w OctetString
The approximate percentage of a port's transmit resources to
be allocated to each transmit queue.  This allows for fine-tuning
of the 'strict priority' configuration.
              
Under strict priority, the highest queue (ctTxQArbNumQueues - 1)
has the highest priority, followed by (ctTxQArbNumQueues - 2), etc.
Queue 0 always has the lowest priority.  All entries in a higher
priority queue will be transmitted before any entries from the lower
priority queues.  This object allows the modification of the strict 
priority scheme so that lower priority queues can be guaranteed some
access to the transmitter.
              
This object is an octet string in which the number of octets corresponds
to the number of transmit queues for each port in this port group,
as indicated by ctTxQArbNumQueues.  The value of the first octet 
represents the number of 'slices' of transmit resources to allocate to 
Queue 0, the second octet represents the number for Queue 1, and so
forth.  The sum of all the octets in the octet string must add up to 
the total number of slices available for the port.
              
For example, on a port having 4 transmit queues and where transmit 
resources are divided into 16 slices, writing an octet string of 
{0x00, 0x04, 0x04, 0x08} would have the following effect:
              
    At least 50% of the frames transmitted are from Queue 3
    At least 25% of the frames transmitted are from Queue 2
    At least 25% of the frames transmitted are from Queue 1
    No frames will be transmitted from Queue 0 until Queues 1, 2 and 3
    are empty.
