For certain variants of that chipset the brcmsmac driver does not
perform well regardless the mode it is in. So could you provide some
more details on the bcm4313 chipset. Can you provide contents from
/sys/kernel/debug/brcmsmac/bcma*/hardware (if that is the correct path).

* Lowest Supported Rate for Unicast Management Frame
From: Chun-Yeow Yeoh @ 2013-07-24 19:36 UTC (permalink / raw)
To: linux-wireless
Hi, all
Just would like know is there any reason of having the unicast
management frame sent at lowest supported rate for the STA even if we
set the basic rate which could be higher than the lowest supported
rate for the STA.

18/21 and 19/21 depend on this patch:
commit 232fde062e0a2cc52e8e18a50cda361b4ba88f34
Author: Daniel Drake <dsd@laptop.org>

mwifiex: fix IRQ enable/disable
which is in wireless.git and wireless-testing.git currently.
We can apply 18 and 19 later after commit 232fde0 is merged back to wireless-next.git.
(I will send you a reminder to merge these two patches once commit 232fde0 is in -next tree.)

* pull request: wireless 2013-07-24
From: John W. Linville @ 2013-07-24 18:04 UTC (permalink / raw)
To: davem; +Cc: linux-wireless, netdev, linux-kernel
[-- Attachment #1: Type: text/plain, Size: 33567 bytes --]
Dave,
This is another batch of fixes intended for the 3.11 stream. FWIW,
this is the first request with fixes from the mac80211 and iwlwifi
trees as well.
Regarding the mac80211 bits, Johannes says:
"Here I have a fix for RSSI thresholds in mesh, two minstrel fixes from
Felix, an nl80211 fix from Michal and four various fixes I did myself."
As for the iwlwifi bits, Johannes says:
"Here I have a fix for debugfs directory creation (causing a spurious
error message), two scanning fixes from David Spinadel, an LED fix and
two patches related to a BA session problem that eventually caused
firmware crashes from Emmanuel and a small BT fix for older devices as
well as a workaround for a firmware problem with APs with very small
beacon intervals from myself."
Along with those:
Arend van Spriel addresses a lock-up and a NULL pointer dereference
in brcmfmac.
Daniel Drake fixes an unhandled interrupt during device tear down
in mwifiex.
Larry Finger corrects a wil6210 build error.
Oleksij Rempel fixes two ath9k_htc problems related to keeping the
driver and firmware in sync.
Solomon Peachy gives us a cw1200 fix to avoid an oops in monitor mode.
Please let me know if there are problems!
Thanks,
John

Thanks Larry,
I have already tried the Ndiswrapper using both the TP-Link provided
Windows XP(64 & 32bit) drivers as well as ones provided by Realtek on
Ubuntu 12.04 and 13.04. Both scenarios freezes the OS. And in scenario
that I save it in conf file for it to load on startup, the OS freezes
on startup. No luck there. Would be interesting to see if anyone else
got it to work using ndiswrapper.

The USB ID has been added to the mainline and stable kernels; however, the
device does not work for me. The latest vendor driver sent privately to me can
make a connection; however, the throughput is less than 1 Mbps. I have not yet
had a chance to investigate as this card is low on my priority list.
I have added the Realtek developer to this reply (Bcc). Perhaps the company has
made some progress; however, when I last contacted them, they did not have an
instance of this particular card. It seems that your only viable option at this
time would probably be the Windows driver with ndiswrapper. I have not tested
this option.

Hi,
I do not own a device with a serial flash chip connected to ssb. This
patch looks ok to me, please apply it.

Hi Jordan,
I added basic adhoc mode support to brcmsmac in 3.10 [0].
This did not got much testing by me. If you want to improve this have
a look on how b43 handles adhoc mode and looking into the initial
brcmsmac commit to staging also helps.

I'm not sure what the expectation is, but those numbers look pretty

In-Reply-To: <CAB=NE6UPz=6NuCMvy5FEM9QBg9rhwFTw0mG2YVTX3r3dLG=1cQ@mail.gmail.com>
I moved over to an ARM embedded proto board and was able to get further.
When suspended, the wireless card appears to stay awake and I can see the
WoW magic-packets as well as other traffic to that NIC. First problem is that
this is kernel 3.0.35 which I read does not yet support wake-on-wireless.
The second question that perhaps one of you can answer is whether or not
the external WAKE_EN# interrupt signal (pin 1 on a mPCIe card) is used to
resume the system, or is the PCIe interrupt expected to resume the system.
I scoped the WAKE_EN# signal but do not see any activity. I also looked at
later drivers, I don't see this signal activated as an interrupt source, but
I'm still looking.
Thank You.

* Fwd: TP-LINK 8200ND

In-Reply-To: <CA+Gu+Kx3RNkenmHD4dGP5NxC1zzq9sxwjdRxuj5qLFCg32DLeQ@mail.gmail.com>
Hi,
I understand there was a thread on linux drivers for TP-LINK8200ND
with rtl8192cu chipset, but it ran cold with no resolution. I was
wondering if there if anyone found a resolution on that.
I have tried installing the drivers provided by realtek as well on
both Ubuntu 12.004 and 13.04. Scorched the internet, and was able to
get it to detect the device but it wont connect to any of the Wireless
networks.
Any help would be helpful.
Thanks
Vihang

So why have you sent this to linux-wireless? Surely you mean to send
it to linux-usb or something.

* IBSS-RSN support for BCM4313
From: Jordan McCarthy @ 2013-07-24 12:32 UTC (permalink / raw)
To: linux-wireless
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi Linux wireless folk,
I am a developer at a non-profit working on a wireless mesh networking
platform, and we've just discovered that we have a fleet of netbooks
with the Broadcom 4313 chipset, one that does not work particularly well
(and sometimes not at all) in ad-hoc mode.
What's more, none of the available drivers seem to support IBSS-RSN,
which is absolutely essential for the requirements of our platform.
Accordingly, I wondered if anyone has any experience trying to get the
BCM4313 to work in an IBSS-RSN configuration, and if not, what is needed
to get either of the following:
- - brcmsmac to support adhoc mode
- - b43 to cover the BCM4313
Many thanks,
Jordan

Thank you for your tests. USB configuration and handlers look similar on
this two firmwares. May be problem is not in FUSB200 and it is clock
related issue so carl9170 do not need reset. - I don't know :(
Can you please test this branch:
https://github.com/olerem/open-ath9k-htc-firmware/commits/next
There is a workaround to reset adapter, right after this bug is
detected. It is really dirty hack, but currently i do not know how to
fix this bug on xhci or on ath9k-htc side.

* [PATCH] ath10k: detect the number of spatial streams supported by hw
From: Michal Kazior @ 2013-07-24 10:36 UTC (permalink / raw)
To: ath10k; +Cc: linux-wireless, Michal Kazior
Until now ath10k assumed 3 spatial streams.
However some devices support only 2 spatial
streams.
This patch improves performance on devices that
don't support 3 spatial streams.

So call user space to load cfg80211 module (alias
net-pf-16-proto-16-family-nl80211) from ctrl_getfamily() with read taken
cb_lock semaphore. That deadlock in modprobe process in
genl_register_family() when try to down_write cb_lock.
This is consequence of commit:
commit fb4e156886ce6e8309e912d8b370d192330d19d3
Author: Marcel Holtmann <marcel@holtmann.org>
Date: Sun Apr 28 16:22:06 2013 -0700
nl80211: Add generic netlink module alias for cfg80211/nl80211
I prepared a possible fix for that (patch below), but I'm not sure if it
do right thing, it can cause other oddity, please test (with
CONFIG_LOCKDEP compiled). I think I would prefer rather remove
autoloading genetlink modules from kernel or use just one lock
in instead of two cb_lock & genl_mutex .

Ok but that requires driver specific support and it's only implemented
on a subset of currently available drivers.
This at least makes the basic tx/rx indication capability a better.
> (Regardless of that, you also have indentation problems in your patch)
Ok, I guess you are referring to the this:
+ led_trigger_blink_oneshot(local->tx_led,
+ &led_delay, &led_delay, 0);
So, are you definitely rejecting this patch or should I fix indentation
and send a v2?
Thanks,
Fabio
