Request conversion

An apparatus comprising:

• circuitry to generate, if an amount of data requested to be transferred by a data transfer request according to a first protocol exceeds a maximum data transfer amount permitted to be requested by a single data transfer request according to a second protocol, one data transfer request according to the second protocol and a data structure, the one data transfer request requesting transfer of a portion of the data, the data structure comprising one or more values identifying, at least in part, another portion of the data, the one or more values in the data structure for providing one or more other values indicating parameters of any data transfer request according to the second protocol, the circuitry also being capable of modifying, at least in part, another data structure associated with the second protocol based, at least in part, upon the one or more values, the another data structure comprising, prior to the modifying, at least in part, of the another data structure, one or more other values indicating, at least in part, one or more parameters of the one data transfer request.

A system comprising:

• a circuit board comprising a circuit card slot;
• and
• a circuit card capable of being coupled to the slot, the card comprising circuitry to generate, if an amount of data requested to be transferred by a data transfer request according to a first protocol exceeds a maximum data transfer amount permitted to be requested by a single data transfer request according to a second protocol, one data transfer request according to the second protocol and a data structure, the one data transfer request requesting transfer of a portion of the data, the data structure comprising one or more values identifying, at least in part, another portion of the data, the one or more values in the data structure for providing one or more other values indicating parameters of any data transfer request according to the second protocol, the circuitry also being capable of modifying, at least in part, another data structure associated with the second protocol based, at least in part, upon the one or more values, the another data structure comprising, prior to the modifying, at least in part, of the another data structure, one or more other values indicating, at least in part, one or more parameters of the one data transfer request.
