/*
 * TBI_ACCEPT macro definition:
 *
 * This macro requires:
 *      adapter = a pointer to struct e1000_hw
 *      status = the 8 bit status field of the Rx descriptor with EOP set
 *      error = the 8 bit error field of the Rx descriptor with EOP set
 *      length = the sum of all the length fields of the Rx descriptors that
 *               make up the current frame
 *      last_byte = the last byte of the frame DMAed by the hardware
 *      max_frame_length = the maximum frame length we want to accept.
 *      min_frame_length = the minimum frame length we want to accept.
 *
 * This macro is a conditional that should be used in the interrupt
 * handler's Rx processing routine when RxErrors have been detected.
 *
 * Typical use:
 *  ...
 *  if (TBI_ACCEPT) {
 *      accept_frame = true;
 *      e1000_tbi_adjust_stats(adapter, MacAddress);
 *      frame_length--;
 *  } else {
 *      accept_frame = false;
 *  }
 *  ...
