ath countrycode

[Jiri Mikulas]

Hello
I have ATH cards Wistron CM9 (AR5213),
I want to set correct countrycode to use correct channels (ETSI)
(channels 1-13 on 11g, channels 100-140 on 11a)
but it's "disabled'

osika:/# sysctl -a dev.ath.0.countrycode=203
sysctl: oid 'dev.ath.0.countrycode' is read only

On most HW wireles AP I can switch country (for example COMPEX WPE54AG-5GHz),
on NetBSD and Linux I can set it too (according to this article http://www.fehu.org/atheros.html )
so I'm little bit suprised, that it's 'forbiden' on Freebsd

I have
 FreeBSD 6.0-STABLE #1: Thu Jan 19 10:40:33 CET 2006
 dev.ath.0.countrycode: 0
 dev.ath.0.regdomain: 0
 hw.ath.hal.version: 0.9.14.9
 ath0: <Atheros 5212> mem 0xff920000-0xff92ffff irq 17 at device 2.0 on pci1
 ath0: Ethernet address: 00:0b:6b:35:46:d7
 ath0: mac 5.9 phy 4.3 radio 3.6

Is there any way to switch countrycode on FBSD please ?

Thanks for reply
