[ath9k-devel] Missing disable_ani in /sys/kernel/debug/ieee80211/phy0/ath9k

[Georgi Kehaiov <nortalion@gmail.com>]

Hello everyone,

I've got an Atheros AR5416 wireless network adapter and I'm experiencing 
the problem described in 
https://bugzilla.kernel.org/show_bug.cgi?id=42092 So I tried to execute 
the official solution (echo 1 > 
/sys/kernel/debug/ieee80211/phy0/ath9k/disable_ani) but for some reason 
or other I am missing the disable_ani file. Is this file located 
somewhere else now? Have I done something wrong? I am running a 3.14.4 
kernel.

Any help will be much appreciated.

Here is some system information you might find useful (kernel config, 
lsmod, module load options, lspci and the contents of 
/sys/kernel/debug/ieee80211/phy0/ath9k):
