Re: [iwlwifi] ipv6 connection problem

Hello all!

After one year I was in need to use ipv6 on wireless and everything is
working ok.
I'm running 15-CURRENT:

---
wlans_iwlwifi0="wlan0"
create_args_wlan0="wlanmode sta regdomain ETSI country PT"
ifconfig_wlan0_ipv6="inet6 accept_rtadv"
ifconfig_wlan0="WPA SYNCDHCP"
rtsold_enable="YES"
---
