|

* 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

|
|
* 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
