In your previous mail you wrote:
What happens if you receive a Neighbour Solicitation Message with
unicast addresses without a source link layer address?
=> what do you mean by "with unicast"?
Do you add an entry with the state set to STALE or INCOMPLETE?
Or do you just ignore it?
=> if the destination is multicast it is just ignored. If the destination
is unicast then the state is not changed and an advertisement is sent
(this can create an entry in the INCOMPLETE state). There is no DoS
issue because the peer must know your link layer address in order to
send an unicast NS.

PS: NUD is a case you can see unicast NS without SLLA, for instance
for the first packet of NUD... RFC 2460 has a SHOULD for SLLA with
a MAY for no SLLA in the unicast case so you can do near what you like (:-).
