am unable to uninstall the modified module( I think its modified one) as
it becomes permanent.
I don't see modprobe showing the path of the currently running module in
Openwrt, is there some other way to find the path ?

hi,
I have upgraded from trunk (aug built) to backfire.
I was getting the rssi value, length of the mpdu captured etc from the
driver to mac80211 using the control buffer.
mac80211 version i was using before( compat-wireless-2011-08-26) had
enough unused bytes to get all of this,
but the mac8021
thanks, I will try that.

hi,
I am modifying mac80211. but when I reboot the router, I get a set of
erros which is due to module dependencies.
lsmod shows : ath9k as the only dependency and I am removing the module
before inserting the modified mac80211 module.
The only other way I to fix this is to remove all the module

hi,
I have been running Openwrt router (netgear).
I have used the command :
iw phy phy1 set channel 40 ht40+/ht40-/ht20
But I have not been able to hear n beacons.
Is it that tcpdump can't decipher n beacons ?
I went through code and saw PRINT_HT_RATES and ieee80211_htrates[] are
defined.

At many times, I set the phy0 interface on the router and on running

hi,
I am trying to add a header in driver ath9k.
I am doing it by adding the header by using skb_put(..) and increment the
skb->data pointer.
Then adding the usual skb content after it by using skb_put().
I finally call netif_rx() to push the skb to upper layers, and can see a
notification that it

I am modifying data in skbuff structure, so it will be convenient for me to
set the things in the driver itself than use Netlink.
What do you think ?

I want to set the monitor mode on in the driver programmatically as there
are some other things i am doing for which the driver is required to be in
the monitor mode.
I wanted to be sure if (is_monitoring, defined in ath_hw) is the correct
flag to be set.
Is it right to set the *changed* variable
hi,
I want to sniff all the packets from the network.
I am setting
sc->sc_ah->is_monitoring = true;
in ath9k_start()
but this gets set to false in in ath9k_config(..).
using the flag : IEEE80211_CONF_CHANGE_MONITOR
Both the functions are defined in main.c in
compat../drivers/net/wireless/ath/ath
(in Monitor mode) interfaces in iwconfig
output.
Shall i use them to create a raw socket and sniff on it ?

I have made a patch to just do a printk(KERN_INFO" ... ");
in ath9k_tasklet().
shall I use any other KERN_ALERT etc options instead ?
But I don't see any output on stdout when I install the image on netgear
router.
It does not have anything in 'cat /var/log/message' also.
Am I missing something ?
ing quilt to do this will make your life much easier :)
