HOW TO enable UAPSD and WMM on ath9k

HOW TO enable UAPSD and WMM on ath9k

[Prigent Xavier MAPS LIS LANNION]

Hello ALL,

I have an AR9280 on debian version 2.6.32. I tried to enable UAPSD and WMM on all queue but I can not. I install compat-
wirelless and load ath9k. 
I saw with iw you can 't enable wmm or UAPSD. I remenbered with iwpriv you could do this but it does not work with this 
driver. 
I saw on" http://wireless.kernel.org/en/developers/Documentation/kerneldoc/include/net/mac80211.h" you could change WMM 
and UAPSD value.So I decide to make change in source and header code 
but it seems to be difficult and I does not understand all.
* @IEEE80211_HW_SUPPORTS_UAPSD:
* Hardware supports Unscheduled Automatic Power Save Delivery
* (U-APSD) in managed mode. The mode is configured with
* conf_tx() operation.

where is conf_tx() operation?

Where I have to make change in order to enable WMM and UAPSD on all queue? 
Is there a CLI command? 

Thanks for your help,

PX

UAPSD is not supported in ath9k.I am saying this based on looking at
init.c of ath9k

You first need to add support for uAPSD to mac80211 for drivers which
need this completely in software, and then add it to ath9k.

Hello,

You said:

Sorry, but I don't understand. What do you add  to mac80211.h?
What do you add to ath9k?

Can you explain step by step how to enable UAPSD on ATH9k or other one driver
please?

I use iw like userspace. It is not possible to define uapsd parameter in  order
to set or get value like iwpriv.

This case will help many people who want to add parameter because it very
difficult fo find something.



Thanks a lot,

Jean
