ipv6_activate_all_interfaces doesn't work on wireless interface.

[Eric L Camachat]

Here is my /etc/rc.conf
ipv6_enable="YES"
#ip6addrctl_enable="YES"
#ip6addrctl_policy="ipv6_prefer"
#ipv6_activate_all_interfaces="YES"
wlans_iwn0="wlan0"
ifconfig_wlan0="WPA DHCP"

rc.d system said ipv6_enable is obsoleted by
ipv6_activate_all_interfaces.
So, I tried to replaced ipv6_enable with ipv6_activate_all_interfaces
and ip6addrctl_*, interface wlan0 will not get ipv6 address from router.

After investigated, that's because of wlan0 didn't add 'accept_rtadv'
ipv6 option.
