- * Shadow tcam DB element
+ * The implementation includes 3 tables per tcam table type.
+ * - hash table

+ * - shadow key table
+ *   - sized to the number of entries requested and is directly indexed
+ *   - the index is zero based and is the tcam index - the base address
+ *   - the key and mask are stored in the key table.
+ *   - The stored key is the AND of the key/mask in order to eliminate the need
+ *   to compare both the key and mask.
+ * - shadow result table
+ *   - the result table is stored separately since it only needs to be accessed
+ *   when the key matches.
+ *   - the result has a back pointer to the hash table via the hb handle.  The
+ *   hb handle is a 32 bit represention of the hash with a valid bit, bucket
+ *   element index, and the hash index.  It is necessary to store the hb handle
+ *   with the result since subsequent removes only provide the tcam index.
+ *
+ * - Max entries is limited in the current implementation since bit 15 is the
+ *   valid bit in the hash table.
+ * - A 16bit hash is calculated and masked based on the number of entries
+ * - 64b wide bucket is used and broken into 4x16bit elements.
+ *   This decision is based on quicker bucket scanning to determine if any
+ *   elements are in use.
+ * - bit 15 of each bucket element is the valid, this is done to prevent having
+ *   to read the larger key/result data for determining VALID.  It also aids
