* 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 seperate actual SG segments.
