 *		* The buffers are not tied down to a particular Channel Adapter. Hence they can

 *		  be sent to or received from any CA. The memory registration is taken care of

 *		  by the SMA.

 *		* The buffers are not required to be maintained by the Subnet Manager. All

 *		  tracking is done by the SMA. 

 *		* Once a buffer is submitted by a SmaPost or SmaSetLocal call to the SMA, it

 *		  will be not returned back.

 *		* There is no rule maintained as to the order of these buffers. The Subnet Manager 

 *		  cannot except the same buffers to be passed in by the SMA.

 *		* All buffers allocated and returned through any send/receive calls hold the same

 *		  size and is equal to the size of a MAD structure of 256 bytes.
