[OpenWrt-Devel] Unable to get TP9343/QCA9561 WLAN working with ath9k (was: ar71xx: fix TP-LINK TL-WR941ND v6 support)

[Matthias Schiffer]

Hi,
as I've already written on the OpenWrt ML, I'm currently porting OpenWrt
to the TP-LINK TL-WR941ND v6, which uses a TP9343 SoC (which is
confusingly part of the QCA956x series). The WMAC identifies as QCA9561
(0x600 rev 0).

I'm unable to get the WLAN working at all. The TX seems to work fine (at
least I can see the beacons when I put the card into AP mode), but RX is
completely dead (iw scan is empty, etc...).

As I'm not familar with ath9k, I need some help debugging this. I'm
using the OpenWrt trunk, which contains a recent version of mac80211
based on wireless-testing, it already contains the patches "ath9k_hw:
fix device ID check for AR956x" and "ath9k: Fix register definitions for
QCA956x".

I've attached a dump of all debugfs information ath9k provides while the
WLAN is configured in IBSS mode in a cell that should be quite active.

Thanks in advance,
Matthias
