In my opinion a proper callback is better. However, the all basic_rates thing
needs a restyling...I think this is a good moment to counter the issue :-)
If nobody else is going to work on this, I will try to propose a solution in
the following days.

Hello everybody,
sorry for the very late response on this topic.
I am performing some tests now using mac80211_hwsim.
I'm first letting wlan0 join the ibss and then I let wlan1 join the same ibss.
In the log I clearly read that the basic rates get updated by means of a
beacon/probe response (actually this is what I expected).
Then I tried to send frames from wlan0 to wlan1 passing through the emulated
link and I can see with "iw dev wlan0 station dump" that the tx rate gets higher
and higher up to 54mbps. Therefore I do not see any problem with the update of
the basic rates.
Am I missing/overlooking something?
@Sujith, do you have a more clear idea of what the problem is?
Cheers,

Hello people, Sujith,
after having read your previous email in the mail-archive (I was not in the
thread since then) I realised that the problem concerns only some drivers. I
better looked at the code and I realised where the problem is.
Thank you.
Cheers,

Hi Pedro and everyone,
Sorry for the thread necromancy, just to close this as 'solved':

Here are the two resulting original patches against compat-wireless of
that time.
http://comments.gmane.org/gmane.linux.drivers.ath9k.devel/9540
https://patchwork.kernel.org/patch/1309961/
They have already been merged upstream since then,
http://git.kernel.org/?p=linux/kernel/git/next/linux-next.git;a=commit;h=e687f61eedab8895e5669cb82cebe0253631cd8c
http://git.kernel.org/?p=linux/kernel/git/next/linux-next.git;a=commit;h=6957802944ec8244cdcfbf50ffbfccf8eceaa413
so any current compat-wireless doesn't exhibit the issue (since
2012-08-21). Thanks Antonio!
in openwrt in particular, it's fixed since (at least, maybe earlier
than) r33331, a rev that updated compat-wireless package.

Hope that helps Pedro and others,
