RE: Ooops... probably IPv6 related, kernel 2.4.4

["Paul Rolland" <rol@as2917.net>]

Some more details :
 - make net/ipv6/addrconf.s gives me some code.
   While trying to compare ksymoops result and this .s file, it seems that
   the problem is probably located in inet6_rtm_deladdr
 - This code (inet6_rtm_deladdr) is compiled if RTNETLINK is selected at
   compile time, and it is on my machine as I need to configure IPv6
addresses
   and I'm using the ip2 package to do that (hell, if someone finds how to
do
   it with ifconfig, pls tell me :

donald /home/rol# ifconfig tap1 inet6 2001:1234:0:ff:1::2
Don't know how to set addresses for family 10.

Regards,
Paul
