1. A network communication device, comprising:

  • a host interface, which is coupled to communicate with a host processor, having a memory, so as to receive a work request to convey one or more data blocks over a network, wherein the work request specifies a memory region of a given data size, and at least one data integrity field (DIF), having a given field size, is associated with the data blocks; and

    network interface circuitry configured to execute an input/output (I/O) data transfer operation responsively to the work request so as to transfer to or from the memory a quantity of data that differs from the data size of the memory region by a multiple of the field size, while adding the at least one DIF to the transferred data or removing the at least one DIF from the transferred data.
