+ * 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--;
