In this test, the TN sends an (un)soliticted NA with the S bit set with 
the expectation that the NUT will update it's NCE.  However, based on 
RFC4861:

      S              Solicited flag.  When set, the S-bit indicates that
                     the advertisement was sent in response to a
                     Neighbor Solicitation from the Destination address.
                     The S-bit is used as a reachability confirmation
                     for Neighbor Unreachability Detection.  It MUST NOT
                     be set in multicast advertisements or in
                     unsolicited unicast advertisements.

So my thoughts are the TN sends a packet that violates the spec (ie: MUST 
NOT).  Can someone explain to me why the table shown in the test 
description expects the NUT to update it's NCE.  It would seem that the 
RFC expects such a packet should get ignored.

Thank you,
