Anyone doing WiFi throughput tests?

Ben Greear — 2012-05-26T03:17:46

We've been doing some tests using Atheros stations and various APs.  The max throughput
we've seen so far is about 237Mbps (received UDP payload on the stations).
(Open-Air, AP about 5 feet away, 3x3 MIMO, HT40, 5Ghz, etc).

We are still running lots of different permutations, but I am interested if
anyone else has any numbers to share (official or otherwise).

Thanks,
Ben

[ANN] QCA swiss army knife

Luis R. Rodriguez — 2012-05-25T20:08:46

To help with simplifying placement of userspace tool development for
QCA for our different drivers we have merged together a few public
development repositories into one, a qca-swiss-army-knife:

Code: git://github.com/mcgrof/qca-swiss-army-knife.git
Wiki: https://github.com/mcgrof/qca-swiss-army-knife/wiki

Of most importance so far is the initval-tools [0], if you used to
send patches for this utility please update your git tree to point to
this new URL, a simple change in the name should let you git pull all
the new changes, you will not have to reset your tree. The other tools
that merged into this tree were  ath-utils and hal-reg-dump, so I've
nuked the old trees from github.

If you have any question please let us know.

[PATCH V2 1/2] ath6kl: Fix race in aggregation reorder logic

Vasanthakumar Thiagarajan — 2012-05-25T10:19:17

There are many places where tid data are accessed without
the lock (rxtid->lock), this can lead to a race condition
when the timeout handler for aggregatin reorder and the
receive function are getting executed at the same time.
Fix this race, but still there are races which can not
be fixed without rewriting the whole aggregation reorder
logic, for now fix the obvious ones.

In order to give the usermode an ability to configure
scan channel times, and as it required for the beacon
reports in the 802.11k standard.

Add to the scan command min/max channel times. Add
min/max passive channel times, since a single scan
can contain both passive and active channels due to
regulatory constraints.

[PATCH v2] mac80211: add op to configure default key id

Yoni Divinsky — 2012-05-24T15:15:12

There are hardwares which support offload of data packets
for example when auto ARP is enabled the hw will send
the ARP response. In such cases if WEP encryption is
configured the hw must know the default WEP key in order
to encrypt the packets correctly.

When hw_accel is enabled and encryption type is set to WEP,
the driver should get the default key index from mac80211.

[PATCH] Fix the Problem of Unreachable Mesh Station when joining from one MBSS to another MBSS

Chun-Yeow Yeoh — 2012-05-24T15:14:24

Mesh station that joins an MBSS is reachable using mesh portal with 6 address frame
by mesh stations from another MBSS if these two different MBSSes are bridged. However,
if the mesh station later moves into the same MBSS of those mesh stations, it is unreachable
by mesh stations in the MBSS due to the mpp_paths table is not deleted. A quick fix is
to perform mesh_path_lookup, if it is available for the target destination, mpp_path_lookup
is not performed. When the mesh station moves back to its original MBSS, the mesh_paths will
be deleted once expired. So, it will be reachable using mpp_path_lookup again.

Felix Fietkau — 2012-05-24T12:32:19

It has been found that active Rx can interfere with stopping tx DMA, which
could result in at least parts of those "Failed to stop Tx DMA!" messages.
Stopping rx before tx should prevent that.

[PATCH v2 22/22] ath9k: improve BT FTP/PAN performance

Sujith Manoharan — 2012-05-24T04:04:09

From: Rajkumar Manoharan <rmanohar-A+ZNKFmMK5xy9aJCnZT0Uw< at >public.gmane.org>

When BT FTP/PAN transmits while WLAN is idle, the one of 9462 chain
often picks up BT's tx signal and starts receiving. If the current
weight is set to be higher than BT tx, BT tx will be aborted and this
also degrades BT performance. Hence lower WLAN rx priority in this
case only when there are no WLAN traffic.

[PATCH v2 17/22] ath9k_hw: fix BT RF performance

Sujith Manoharan — 2012-05-24T04:03:37

From: Rajkumar Manoharan <rmanohar-A+ZNKFmMK5xy9aJCnZT0Uw< at >public.gmane.org>

When software rfkill is triggered, before put the chip in reset
state, give LNA and SPDT control to BT to make sure BT can have
good RF performance.
