Up till now the DFU maximum file size (to be written to e.g. eMMC) was different from the DFU data buffer size. It caused errors when one buffer was smaller than data to be written. Now, the maximum DFU file size is equal to default DFU buffer size. In spite of this, user is still able to manually adjust those default values.
