Subject: [Bugme-new] [Bug 4482] New: natsemi: incorrect initialization of IPv6
Neighbor-discovery multicast
http://bugme.osdl.org/show_bug.cgi?id=4482
Summary: natsemi: incorrect initialization of IPv6 Neighbor-
discovery multicast
Kernel Version: 2.6.11.7
Status: NEW
Severity: normal
Owner: jgarzik@xxxxxxxxx
Submitter: svallet@xxxxxxxxx
Distribution: Debian Sarge (testing)
Hardware Environment:
Arch is PowerPC/BeigeG3
Problematic NIC has a DP83815 chipset (Netgear FA311)
Software Environment:
iproute2/ifconfig
Problem Description:
"ifconfig eth0 up" *apparently* allows multicast on the device :
# ifconfig eth0
...
UP BROADCAST RUNNING MULTICAST
...
# ip maddr show
...
1: eth0
link 33:33:ff:be:0a:ed
link 33:33:00:00:00:01
...
inet6 ff02::1:ffbe:aed
inet6 ff02::1
However, the NIC does *not* reply to neighbor-sollicitation multicasts, neither
on 33:33:00:00:00:01 (ping6 ff02::1) or on the sollicited-node multicast.
It *is* however responding *after* being brought in promiscuous mode (using
tcpdump) or an "ifconfig eth0 multicast" has been issued. Shuting down and up
brings the problem back again
Steps to reproduce:
# ifconfig eth0 down
# ifconfig eth0 up
