+ * TBI_ACCEPT macro definition:
+ *
+ * This macro requires:
+ *      a = a pointer to struct e1000_hw
+ *      status = the 8 bit status field of the Rx descriptor with EOP set
+ *      errors = 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
+ *      min_frame_size = the minimum frame length we want to accept.
+ *      max_frame_size = the maximum 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;
+ *  }
