[ath9k-devel] AR9287 ; 2-wire coexistence expected behavior

[sandeep suresh <sandeep.suresh@yahoo.co.in>]

Hello Mr.Adrian,
????Greetings! I resumed my experiments with 2-wire co-existence with AR9287 in WiFi AP mode.
I was able to see that WLAN_STATUS signal being suppressed when BT_ACTIVE is enabled. I used a 100ms On and 100ms Off (Period = 200ms; 50% dc) for BT_ACTIVE. Just want to confirm the following before ensuring that I am seeing the expected behavior:
?
1. As I am running the WiFi AP with co-existence, other WiFi clients are connected to my AP. by means of diagnsosis (I have enabled diagnosis with modprobe ath9k btcoex_enabled=1 diag=0xffffffff), how can I find out if any WiFi clients are loosing connection and re-connecting back to AP.
?
2. How can I come to know if any of the beacons in WiFi AP mode are getting missed? Diagnosis messages that I can look at.
?
3. As diagnosis is enabled I see the following....is this a concern as there is disable and enable of IER?
<7>ath: disable IER
<7>ath: AR_IMR 0x918104b0 IER 0x1
<7>ath: tx queue 2 (4bfc09c4), link ffde09c4
<7>ath: enable IER
<7>ath: Enable TXE on queue: 2
<7>ath: disable IER
<7>ath: AR_IMR 0x918104b0 IER 0x1
?
4. How can I come to know if the ath9k drivers are getting reset and reinitializing? 
?
Thanks & Regards
Sandeep Suresh.

Ok.

c). If there's some strong signal in the air that exceeds the CCA
threshold but isn't a decodable wifi signal, rx_clear is cleared.
