Subject: zd1211rw (2.6.26.5) and ipv6
Hello,
After a little investigation (see after), I came to the conclusion
there was something strange with the zd1211rw wifi driver (or
maybe mac80211-based ones like it happened in the past ?) and ipv6
(at least with autoconfiguration).
I am on Archlinux with kernel 2.6.26.5 kernel behind a router
connecting me to internet by ipv4 and ipv6.
After a little discussion with John W. Linville on irc, he
redirected me to this mailing list.
The idea is that I connect to a wireless network with wpa
protection, get my ipv4 address by dhcp and my ipv6 address by
autoconfiguration : the ip is ok, the routes are goods, I can
ping6 myself, I can ping6 the router (the next hop for default
route) but I can't go out of this network.
If I do the same but with ethernet (same router serving both
ethernet and wifi), all the ip configuration, routes, neighbors
are the same, but I can go out on the net.
Nothing in dmesg.
Of course ipv6 works on other boxes (I tried a windows on a
laptop, and the routes used are the same too)
This is what I have with both ethernet and wifi :
First wifi :

That's all for now, I hope nothing is missing.
Thanks you for your help,
