Hi Panos,

RADVD does not send a response to every solicitation and there is a random
delay (between 0 and 1/2 seconds I think).  The random delay is called for
in RFC 2461 (http://www.faqs.org/rfcs/rfc2461.html).  It's not really that
important, but it cuts down on the number of broadcast advertisements

RADVD should NOT respond to every solicitation it sees (we don't want to
flood the network with useless advertisements).  However, if you're finding
you don't get an address fast enough, then you may have a bug or
configuration issue.
