[ath9k-devel] ath9k and CRDA messages in logs

[Alex Buell]

I have the following which I imported directly from China:

02:02.0 Network controller [0280]: Atheros Communications Inc. AR922X
Wireless Network Adapter [168c:0029] (rev 01)
Subsystem: Atheros Communications Inc. Device [168c:2091]
Kernel driver in use: ath9k
Kernel modules: ath9k

As I am in the UK, I set up the options for the ath9k modules:

options cfg80211 ieee80211_regdom=EU

The first time the modules are loaded I get the following which is
correct:

Aug 24 13:26:25 lithium kernel: [930896.157956] cfg80211: Calling CRDA to update world regulatory domain
Aug 24 13:26:25 lithium kernel: [930896.332831] cfg80211: World regulatory domain updated:
Aug 24 13:26:25 lithium kernel: [930896.332841] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp)
Aug 24 13:26:25 lithium kernel: [930896.332849] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)
Aug 24 13:26:25 lithium kernel: [930896.332884] cfg80211: Calling CRDA for country: EU

But subsequently I get the following:

Aug 24 13:26:28 lithium kernel: [930899.490068] cfg80211: Calling CRDA to update world regulatory domain
Aug 24 13:26:28 lithium kernel: [930899.503157] cfg80211: World regulatory domain updated:
Aug 24 13:26:28 lithium kernel: [930899.503167] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp)
Aug 24 13:26:28 lithium kernel: [930899.503177] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)
Aug 24 13:26:28 lithium kernel: [930899.503226] cfg80211: Calling CRDA for country: 97
Aug 24 13:26:31 lithium kernel: [930902.660047] cfg80211: Calling CRDA to update world regulatory domain
Aug 24 13:26:31 lithium kernel: [930902.668199] cfg80211: World regulatory domain updated:
Aug 24 13:26:31 lithium kernel: [930902.668207] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp)
Aug 24 13:26:31 lithium kernel: [930902.668216] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)
Aug 24 13:26:31 lithium kernel: [930902.668257] cfg80211: Calling CRDA for country: 97
Aug 24 13:26:34 lithium kernel: [930905.820055] cfg80211: Calling CRDA to update world regulatory domain
Aug 24 13:26:34 lithium kernel: [930905.832380] cfg80211: World regulatory domain updated:
Aug 24 13:26:34 lithium kernel: [930905.832389] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp)
Aug 24 13:26:34 lithium kernel: [930905.832397] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)
Aug 24 13:26:34 lithium kernel: [930905.832431] cfg80211: Calling CRDA for country: 97

This keeps repeating. What is going on and is there anything I can do to
make it set up with the EU settings instead of country 97's settings
which aren't correct. Also is there anyway I can squelch this? It's
filling up logs (although they do get rotated I'd rather not have it
keep writing the same info over and over again)

Thanks for any help given.

hi i have little knowledge about this, but saw something useful in the wiki
