Hi,
Two oddities with wlan0:
=46rom dmesg:

First, since I updated to FreeBSD 10, the system does not seem to be
counting ifOutOctets, but does count ifInOctets. Looking at it with
netstat:
$ netstat -I wlan0 -b
Name Mtu Network Address Ipkts Ierrs Idrop Ibytes=
Opkts Oerrs Obytes Coll
wlan0 1500 <Link#7> 00:24:2c:36:90:55 2715328 56 0 930414649=
3549300 2965 0 0
wlan0 1500 192.168.2.0 spandex 266442 - - 183610706=
186618 - 77852137 -
wlan0 1500 fe80::224:2cf fe80::224:2cff:fe 1 - - 72=
17 - 1304 -
wlan0 1500 2001:470:d:4d 2001:470:d:4de::1 0 - - 0=
1 - 136 -
Is this a bug, or am I polling the wrong interface for Obytes? When I
look at ath0, it does not seem to be counting bytes out either.
Second, for whatever reason rtadvd does not seem to be advertising on
wlan0. My /etc/rtadvd.conf:
wlan0:\
:addrs#1:addr=3D"2001:470:d:4d3::":prefixlen#64:tc=3Dether:
If I /etc/rc.d/rtadvd restart, then route advertisements begin
to flow.
$ sudo rtadvctl show

Thoughts?
