Streamline testing of 802.11 drivers

Streamline testing of 802.11 drivers

[Luis R. Rodriguez]

I've mentioned this to a few but here it is out to everyone. So as you
know we have a lot of work ahead of us for linux wireless development.
To help speed this up, we at Winlab, would like to start hosting a
testbed for linux wireless development, open to the public. Short term
goals would be to start off a couple of nodes for each driver
currently under development like bcm43xx, zd1211, rt2x00, ipw3945,
ipw2200 and the like, and a provide a set streamlined tests we can use
to really put to test the drivers and stacks.

This wouldn't be easy if we didn't have infrastructure but we already
do. Our grid consists of 400 nodes with 2 wireless cards each and 3
ethernet ports (one for control) --
http://orbit-lab.org/wiki/Tutorial/Testbed. 90% of our nodes use the
atheros 5213 chipset and the rest ipw2200s. We'd like to expand this
with the more wireless cards currently being worked on for linux.

Right now we have zome zd1211s so we'll start with that (I'll start
working on a port to d80211) but will try to accomodate other nodes as
we get more wireless cards. We will need some help too though, to
streamline the testing. If you have ideas or would like to contribute
please let me know. We can purchase wireless cards but if you already
have reliable confirmed wireless cards which can be used for putting
into the testbed let me know.

This would be really interesting. :)

I'll discuss this in the rt2x00 team, and see if we can donate some
hardware.

Great just let me know. MiniPCI would be fit best.

I have a spare Linksys WPC54G Cardbus adapter with an early Broadcom BCM4306 chip in it. The LEDS do 
not work, but everything else is OK.

Thanks Larry -- I'm sorry for not mentioning in the original thread
but basically miniPCI and USB is what we can slap onto our nodes so
far. We'll have to figure something out for Cardbus..  I searched and
it seems there some miniPCI bcm4306. I'll see if we can come up with a
cardbus solution though as I'm sure there's gotta be some card which
don't ship in other form factors. Will get back to you on that.

I'd say most cards come at least in USB or miniPCI as they are/were
mostly for use in laptops. bcm43xx certainly does, we still have some
funds that were donated so we could probably fund a few bcm43xx cards
for the testbed.

Excellent, will make arrangements with you off the list.
