[6bone] icmp ttl exceeded, not for packets > 112 (FreeBSD-5.3)

[Armin Arh]

Hi,

we have found an interesting behaviour about ttl exceeded with
FreeBSD-5.3: Packets larger than 112 bytes do not get answered
with this error.
In the following output, bge0.gw-tunnel-a.v6.schlund.net is our
FreeBSD- box.
(Second parameter of traceroute6 is packet size)

armin at nero traceroute6 test.rot13.de 112
traceroute6 to test.rot13.de (2001:8d8:81:550::1) from 2001:8d8:41::6, 64 hops max, 112 byte packets
