* We cannot tell prior to getting IOC facts how big the IOC's request
* area is. Because of this we cannot tell at compile time how many
* simple SG elements we can fit within an IOC request prior to having
* to put in a chain element.
*
* Experimentally we know that the Ultra4 parts have a 96 byte request
* element size and the Fibre Channel units have a 144 byte request
* element size. Therefore, if we have 512-32 (== 480) bytes of request
* area to play with, we have room for between 3 and 5 request sized
* regions- the first of which is the command plus a simple SG list,
* the rest of which are chained continuation SG lists. Given that the
* normal request we use is 48 bytes w/o the first SG element, we can
* assume we have 480-48 == 432 bytes to have simple SG elements and/or
* chain elements. If we assume 32 bit addressing, this works out to
* 54 SG or chain elements. If we assume 5 chain elements, then we have
* a maximum of 49 separate actual SG segments.
