Hi, Abe-san.

For 1st question)

    You can use them for your environment.
    Your list satisfies IPv6 Ready Logo requirements,
    but I have a suggestion about it.
    I feel that using other OS (ex, Open BSD) is better than KAME
    because KAME already had stopped the activity long time ago.
    If you have the product other than free software OS,
    using the product is the best.

For 2nd question)

    It is the correct behavior according to RFC 4861.

    7.2.2.  Sending Neighbor Solicitations
    ------------------------------------------------------------------------
    3440    While waiting for address resolution to complete, the sender MUST,
    3441    for each neighbor, retain a small queue of packets waiting for
    3442    address resolution to complete.  The queue MUST hold at least one
    3443    packet, and MAY contain more.  However, the number of queued packets
    3444    per neighbor SHOULD be limited to some small value.  When a queue
    3445    overflows, the new arrival SHOULD replace the oldest entry.  Once
    3446    address resolution completes, the node transmits any queued packets.
    ------------------------------------------------------------------------

Thanks,
