wlan0/iwn: no upload statistics

[bycn82]

Just tell "the command is not working" cannot help in resolving the problem. Could you please provide more detail? for example.

1. Firewall can tell you the total in/out traffic
2. The systat -ifstat result.
3. Netstat information

In previous email, the guy provided the below information.

Can you please confirm whether the "377.757 MB" is `in` or `out` traffic?
