/proc/net/wireless vs. iwconfig

I noticed is that /proc/net/wireless shows other values than iwconfig does.
$ cat /proc/net/wireless
Inter-| sta-| Quality | Discarded packets | Missed | WE
face | tus | link level noise | nwid crypt frag retry misc | beacon | 22
eth1: 0000 0 0 0 0 0 0 0 0 0
which looks like there is not network. But in fact there is, as
iwconfig shows correctly:
eth1 AR6000 802.11g ESSID:"adhoc"
Mode:Ad-Hoc Frequency:2.457 GHz Cell: 52:73:CF:8F:CE:5B
Bit Rate=1 Mb/s Tx-Power=15 dBm Sensitivity=0/3
Link Quality:195/94 Signal level:-156 dBm Noise level:-98 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:18 Invalid misc:0 Missed beacon:0
This is in a ad-hoc network, but the same happens when i connect to a
access point. I looked into the source and it looks like this
if ((ar->arWmiReady == FALSE) || (in_atomic())
(line 2104 in ar6000_drv.c) is always true and because of that the
values printed in /proc/net/wireless are always defaulted to 0.
Why is that, and where does iwconfig get it's data from?
