[b43] Station statistics

[Matteo]

Hi all,
I am trying to find some data link statistics  like tx/rx packets, tx/rx
byte and
tx retries.

I found to use iw wlan0 station dump some interesting values, but I have a
doubt.

do you know why the #packets and bytes found with iw wlan0 station dump are different
if compared with cat /proc/net/dev ?

inactive time:    948 ms
   rx bytes:    12793798
   rx packets:    55705
   tx bytes:    72610
   tx packets:    377
   tx retries:    20
   tx failed:    2
   signal:      -33 dBm
   signal avg:    -33 dBm
   tx bitrate:    36.0 MBit/s
   authorized:    yes
   authenticated:    yes
   preamble:    long
   WMM/WME:    yes
   MFP:        no
   TDLS peer:        no
