This object reflects an explicit configuration of the
maximum number of cells that may occupy this queue.
If the value of this object is 0, the maximum size in effect
is a default value calculated by software.
Prior to any user configuration, the value of this object
is 0. The actual maximum size is reflected in the object
sharedMemRmIfOutputQInstalledMaxSize (and is a default value
calculated by software). Setting this value to 0 causes the
size to assume it's default value. When changing a port that
is up, must be set in conjunction with the force object
(sharedMemRmIfOutputQMaxSizeForce) to take effect.
