    * 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;
    *  }
