/* RAUHTD - Router Algorithmic LPM Unicast Host Table Dump Register
* ----------------------------------------------------------------
* The RAUHTD register allows dumping entries from the Router Unicast Host
* Table. For a given session an entry is dumped no more than one time. The
* first RAUHTD access after reset is a new session. A session ends when the
* num_rec response is smaller than num_rec request or for IPv4 when the
* num_entries is smaller than 4. The clear activity affect the current session
* or the last session if a new session has not started.
