Re: [iwlwifi] ipv6 connection problem

I should have mentioned that my wireless AP isn't your typical AP.
It's running HardenedBSD 13-STABLE on a PC-Engines APU2 with an
Atheros WNIC.

Here's the relevant configs on the WAP:

==== begin rc.conf ====
ifconfig_igb0="DHCP"
ifconfig_igb0_ipv6="inet6 accept_rtadv"

wlans_ath0="wlan0"
create_args_wlan0="wlanmode hostap mode 11a up"
ifconfig_wlan0="HOSTAP"

cloned_interfaces="bridge0"
ifconfig_bridge0="addm igb0 addm wlan0 span igb1 up"
==== end rc.conf ====

==== begin hostapd-wlan0.conf ====
interface=wlan0
ctrl_interface=/var/run/hostapd-wlan0
ctrl_interface_group=wheel
ssid=[redacted]
wpa=2
wpa_passphrase=[redacted]
wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP
==== end hostapd-wlan0.conf ====
