(usagi-users 02442) 2.4.20 + usagi 23062003: can not ping link local

[Miek Gieben <miekg@xxxxxxxxx>]

Hello, 

i'm running linux 2.4.20 + usagi patch from 23-06-2003. I'm trying to
setup ipv6 here, but without luck (also see my "stuck with 2.4.21" mail
to the list).

I've tried to simplify the problem, currently the situation is that I 
cannot ping the link local address:

# ip -6 a l
1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue 
    inet6 ::1/128 scope host 
3: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 100
    inet6 fe80::280:48ff:feb3:26eb/64 scope link 

# ping6 -I eth0 -c 1 fe80::280:48ff:feb3:26eb
PING fe80::280:48ff:feb3:26eb(fe80::280:48ff:feb3:26eb) from
fe80::280:48ff:feb3:26eb eth0: 56 data bytes

--- fe80::280:48ff:feb3:26eb ping statistics ---
1 packets transmitted, 0 received, 100% loss, time 0ms

the routing looks ok to me:
# ip -6 ro sh
fe80::/64 dev eth0  proto kernel  metric 256  mtu 1500 advmss 1440
ff00::/8 dev eth0  proto kernel  metric 256  mtu 1500 advmss 1440
unreachable default dev lo  metric -1  error -101

just the minumum for this usage.

On another machine on my network this all just works (even without usagi). Can
somebody tell me what i'm doing wrong here?

Doing this with a tcpdump running along:
# tcpdump -p -v -n -i any ip6 &
[2] 2140
tcpdump: listening on any

# ping6 -I eth0 -c 1 fe80::280:48ff:feb3:26eb
PING fe80::280:48ff:feb3:26eb(fe80::280:48ff:feb3:26eb) from fe80::280:48ff:feb3:26eb eth0: 56 data bytes

why are these sollicitations send?
