  125  * TBI_ACCEPT macro definition:
  126  *
  127  * This macro requires:
  128  *      a = a pointer to struct e1000_hw
  129  *      status = the 8 bit status field of the Rx descriptor with EOP set
  130  *      errors = the 8 bit error field of the Rx descriptor with EOP set
  131  *      length = the sum of all the length fields of the Rx descriptors that
  132  *               make up the current frame
  133  *      last_byte = the last byte of the frame DMAed by the hardware
  134  *      min_frame_size = the minimum frame length we want to accept.
  135  *      max_frame_size = the maximum frame length we want to accept.
  136  *
  137  * This macro is a conditional that should be used in the interrupt
  138  * handler's Rx processing routine when RxErrors have been detected.
  139  *
  140  * Typical use:
  141  *  ...
  142  *  if (TBI_ACCEPT) {
  143  *      accept_frame = true;
  144  *      e1000_tbi_adjust_stats(adapter, MacAddress);
  145  *      frame_length--;
  146  *  } else {
  147  *      accept_frame = false;
  148  *  }
  149  *  ...
