I am adding the following lines to the code :

I don't even get these printk(() output on dmesg !
when i do :

I am following exactly what you have said above.
I am not doing package/mac80211/{clean,__compile}
after package/mac80211/update
and loading the image on the router.
Please help, I am out of creativity of trying anything new on
this thing.
You're probably editing in the wrong place. OpenWrt does not use
mac80211 or ath9k from build_dir/linux-ar71xx___generic/linux-2.6.39.4.
What you're interested in is in
build_dir/linux-ar71xx___generic/compat-wireless-*/
I want to modify compat wireless driver.
this is what documentation I am following
http://wiki.openwrt.org/doc/devel/patches .
More precisely this :
# make package/mac80211/{clean,prepare} V=99 QUILT=1
# cd build_dir/linux-ar71xx_generic/compat-wireless-2011-08-10/
# quilt push -a
# quilt new my_changes.patch
# quilt edit drivers/net/wireless/ath/ath9k/files
# quilt refresh
# cd ../../../ && make package/mac80211/update
After above I copy the image on the router.
The changes are reflected in the code in
build_dir/linux-ar71xx/compat../drivers/net/...ath9k/init.c
I suggest you read up on how to use quilt for managing patches on
packages, the OpenWrt package that this build dir belongs to is
package/mac80211.
After you modify it, don't run make package/mac80211/clean, that'll
throw away all of your modifications :)
I am running mac80211/update as the last command before uploading the
image on router.
I think that should be it, but I don't get printk() outputs.
If you reflash, then you need to rebuild the firmware before you do so.
Otherwise you could just use make package/mac80211/compile and copy
bin/ar71xx/packages/kmod-ath* to the router and install it there.
