+ * For MAC address comparison speedup reasons, we introduce a trick.

+ * This pair of integers is compared with MAC addresses in the
+ * hash table, which are stored also in form of pairs of integers
+ * (in `cmp' array). This is quick as it requires only two elementary
+ * number comparisons in worst case. Further, we take advantage of
+ * fact that entropy of 3 last bytes of address is larger than entropy
+ * of 3 first bytes. So first we compare 4 last bytes of addresses and
+ * if they are the same we compare 2 first.
