Bug ID: 197057
Summary: Netstat -w1 and systat -ifstat show no out traffic
Product: Base System
Version: 11.0-CURRENT
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: wireless
Assignee: freebsd-wireless@FreeBSD.org
Reporter: gre...@freebsd.org
This seems to be a known issue, I couldn't find anything in bug database
though. I experienced it using ath on 11-CURRENT, but it doesn't seem limited
to this:
https://lists.freebsd.org/pipermail/freebsd-current/2014-June/050631.html
Examples are on a machine using ath0, wlan0 and wpa_supplicant, basically:
wlans_ath0="wlan0"
ifconfig_wlan0="WPA DHCP"
in /etc/rc.conf, while transferring about 10GB of data.
systat -iface:
wlan0 in 73.489 KB/s 95.061 KB/s 624.790 MB
out 0.000 KB/s 0.000 KB/s0.000 KB
netstat -w1:

netstat -w1 -Iwlan0:

netstat -w1 -Iath0:

For comparison, this is what this looks like at the receiving end:
