/* Sometimes Spirit1 seems to NOT deliver (correctly) the 'IRQ_RX_DATA_READY'
 * event for packets which have a length which is close to a multiple of
 * RX FIFO size. Furthermore, in these cases also the content delivery seems
 * to be compromised as well as the generation of RX/TX FIFO errors.
 * This can be avoided by reducing the maximum packet length to a value which
 * is lower than the RX FIFO size.
 *
 * Enable beyond macro if you want to use the version of the driver which avoids
 * FIFO overflows by reducing packet length.
 *
 * NOTE: the non delivery of event 'IRQ_RX_DATA_READY' MUST still be
 *       investigated further deeply (both on HW & SW level)!
