Problem compiling ath5k

Problem compiling ath5k

[Fabio Venturi]

Hello to the list,
I'd like to try the ath5k kernel module for my Atheros AR2413 Wireless Card
so I downloaded the compat-wireless-2.6.tar.bz2 
I'm running a 2.6.24.2 kernel (the laste stable),
but the compile stage ends immediately:

I'm missing linux/pm_qos_params.h
Where can I get it?
The directory /usr/include is a symlink to /usr/src/linux/include

Thank you in advance for any advice.
Best regards,
Fabio

OK,
now the driver compile and load without any problem and
the wlan0 and master0 devices are created.
There are no error in dmesg, but I can't scan for stations,
iwlist wlan0 scan
says there are no active stations.
Do I need extra modules for scanning?
I'm using an Atheros AR2413, is this device supposed to work with
the ath5k module?
Thank you in advance for any help,
regards,
Fabio

These issues are being addressed with ipw, essentially we need some
items ported over.

You need to turn your interface up first:

ip link set wlan0 up

Or

ifconfig wlan0 up

Where can I get that preview snapshot of ath5k? 
I could test it.

I'll stay tuned as you suggest.

The interface is up and running, but somehow it seems missing
the beacon packets.

AR2413 is not yet properly supported in ath5k. The last statement about this is from 15.02.2008, where Nick Kossifidis said:

"Sorry for delaying the relevant patches, i'm working with the 2413
card i got from Mike to make it work and it'll take some time (not as
easy as i thought, i probably miss something)..."

I am waiting for this PHY to get supported, too.
