Re: [PATCH v2] wl1251: add sysfs interface for bluetooth coexistence mode configuration

Pali Rohár [off-list ref] writes:

Port the bt_coex_mode sysfs interface from wl1251 driver version included
in the Maemo Fremantle kernel to allow bt-coexistence mode configuration.
This enables userspace applications to set one of the modes
WL1251_BT_COEX_OFF, WL1251_BT_COEX_ENABLE and WL1251_BT_COEX_MONOAUDIO.
The default mode is WL1251_BT_COEX_OFF.
It should be noted that this driver always enabled bt-coexistence before
and enabled bt-coexistence directly affects the receiving performance,
rendering it unusable in some low-signal situations. Especially monitor
mode is affected very badly with bt-coexistence enabled.

I'm resending this patch for review again as after two years there is no
nl80211 interface for bt coex and wl1251 on Nokia N900 needs it. Once
there will be common interface for bt coex I can rewrite my patches, but
I do not want to wait another 2 years...

It doesn't work like that. Wireless drivers cannot have custom
interfaces via sysfs, all configuration has to go through cfg80211.
Instead of waiting two years you could have added it yourself.
