This attribute specifies the maximum size of the DCS Agent's
queue for this data stream on this LP. For more details on the
defaults and other information, refer to the parent component's
agentQueueSize attribute.
The size should be set to 0 if absolutely no data is to be accepted
from applications. There are threshold alarms based on the value of
the Agent's currentQueueSize attribute (a Set when the queue
becomes 75% full and a Clear after dropping back to 50% full).
To properly determine what to set this to, consult the 'Magellan
Passport Engineering Notes and Guidelines'.
