[Patch] DAD interval

[YOSHIFUJI Hideaki / 吉藤英明 <yoshfuji@xxxxxxxxxx>]

Sorry for the delay...
We, USAGI Project, will provide you 3 or 4 patches (at least)...


This fixes interval between DAD packets.

[1] RFC2042

5.4.2.  Sending Neighbor Solicitation Messages
:
   To check an address, a node sends DupAddrDetectTransmits Neighbor
   Solicitations, each separated by RetransTimer milliseconds. The
   solicitation's Target Address is set to the address being checked,

[2] RFC2041

6.3.2.  Host Variables
:
        RetransTimer   The time between retransmissions of Neighbor
                       Solicitation messages to a neighbor when
                       resolving the address or when probing the
                       reachability of a neighbor.
