  94 * TBI_ACCEPT macro definition:
  95 *
  96 * This macro requires:
  97 *      a = a pointer to struct e1000_hw
  98 *      status = the 8 bit status field of the Rx descriptor with EOP set
  99 *      errors = the 8 bit error field of the Rx descriptor with EOP set
 100 *      length = the sum of all the length fields of the Rx descriptors that
 101 *               make up the current frame
 102 *      last_byte = the last byte of the frame DMAed by the hardware
 103 *      min_frame_size = the minimum frame length we want to accept.
 104 *      max_frame_size = the maximum frame length we want to accept.
 105 *
 106 * This macro is a conditional that should be used in the interrupt
 107 * handler's Rx processing routine when RxErrors have been detected.
 108 *
 109 * Typical use:
 110 *  ...
 111 *  if (TBI_ACCEPT) {
 112 *      accept_frame = true;
 113 *      e1000_tbi_adjust_stats(adapter, MacAddress);
 114 *      frame_length--;
 115 *  } else {
 116 *      accept_frame = false;
 117 *  }
 118 *  ...
