On Fedora 6 (kernel 2.6.20, no mac80211) it was OK. I get "wlan0: duplicate address detected!" on dmesg when the kernel is trying to autoconfigure a global address. I suppose this is caused by the IPv6 stack seeing my own ICMPv6 neighbor solicitation and thinking it was originated by someone else: 08:46:21.762807 00:02:72:5b:dc:28 > 33:33:ff:5b:dc:28, ethertype IPv6 (0x86dd), length 78: (hlim 255, next-header: ICMPv6 (58), length: 24) :: > ff02::1:ff5b:dc28: [icmp6 sum ok] ICMP6, neighbor solicitation, length 24, who has 2001:708:10:90:202:72ff:fe5b:dc28 Strangely, the same error isn't printed with the link-local address which uses the same EUI-64. z1211rw Wiki seems to imply that this might be an issue in generic mac80211 code: http://www.linuxwireless.org/en/users/Drivers/zd1211rw/mac80211Issues It'd be nice to get this fixed.
