two freebsd 10 wlan0 oddities

[Matthew Luckie]

Hi,

Two oddities with wlan0:

From dmesg:

ath0: <Atheros 9285> mem 0xfeaf0000-0xfeafffff irq 18 at device 0.0 on pci3

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="2001:470:d:4d3::":prefixlen#64:tc=ether:

If I /etc/rc.d/rtadvd restart, then route advertisements begin
to flow.

$ sudo rtadvctl show
Password:
wlan0: flags=<UP,TRANSITIVE,PERSIST> status=<RA_SEND> mtu 1500
        DefaultLifetime: 30m
        MinAdvInterval/MaxAdvInterval: 3m20s/10m

Thoughts?
