Legacy driver dead lock problem

Hello

I think I found a deadlock problem in the legacy driver. It may no be of a
huge interest, as there is a timeout (10 seconds) but here it is:

- In zd1205_ioctl : one of the first line is protection using
down(&macp->ioctl_sem);

- if you want to "iwconfig xxx mode master" there is a time-out loop of 10
secs which will be freed when dot11Obj.bChScanning is true.

- dot11Obj.bChScanning is set to true in kevent processing, 

-  kevent processing which start with a ..... down(&macp->ioctl_sem)

>From a user point of view it looks like that the process configuring the
driver is dead (no reaction anymore) and watchdog will kicked in.

I'am working on a patch for this.

Another point : in zd1205_ioctl_setmode , there are registers writes (AP,/AP
filtering), that don't look in the right place. For me they should be setup
"protectively" in update_card_settings event. Can anyone confirm? If so I'll
also provide a patch.

Regards - Fab

zd1211rw mesh speed limited at 1Mbit?

Hi,

we are testing a mesh network with open80211s (www.o11s.org) in a wireless-testing kernel. We are using
A-link WL54USB adapters with the zd1211rw driver. Mesh seems to work fine, but the connection is
established only with 1Mbit/s (we are getting ~80kb/s transfer rates with FTP). When using adapters in
"regular" WLAN, we were able to get much faster speeds (7-10Mbit).

Is this a driver feature? Is it possible to increase speed in mesh mode?

Thanks in advance,
- Petri Virkkala

Sorry for the double post. 

Here's the result of "sudo iw dev mesh station dump" in a two link mesh network:

Station xx:xx:xx:xx:xx:xx (on mesh)
	inactive time:	64 ms
	rx bytes:	5699474
	rx packets:	9166
	tx bytes:	253024
	tx packets:	2597
	tx bitrate:	1.0 MBit/s
	mesh llid:	29759
	mesh plid:	28168
	mesh plink:	ESTAB

"tx bitrate" is here 1.0MBit/s as we suspected. Is there a way to change/force it to faster speeds?

zd1211b Signal Values in monitor mode

Hello everyone. I just enrolled this list because i am interested in 
the development of this chipset under linux.
I myself have a zd1211b based usb wifi card (TL-WN422G) and i used 
under ubuntu 8.10 with a patched driver, so it recognizes de RF 
(UW2453).
I was trying to use this device with kismet, and i noticed some 
things:
-Signal Values Are not in DB
-Noise values are always 0 (actually, this happens with my iwl3945 
internal wifi card too.

I wanted to ask you if someone knows why is that. I am interested in 
doing signal surveys with this card, and wanted to know if that is 
possible.
Is there any way i can help with this? If the answer is yes, can 
someone point me to the direction where i can find some technical info 
about the zd1211b chip?

Thanks for your help!
Ricardo
