You'll have to ask Felix and others, but I think they're more generic
APIs to support things like AR9285 (and the relevant AR9300/AR9400
series NICs) which implement 1x1 but have "classic" style antenna
diversity.
Also, as I've discovered, you _can_ glue an antenna switch onto the
side of a MIMO NIC. Eg, I have an AR9220 based NIC (2x2:2) which has
three antennas, both the second and third are connected to chain 1 via
an antenna switch.

In-Reply-To: <20111015093902.GA23520@ecki>
I've found some perhaps relevant bits of code here which force the
chip into and out of reset/sleep states.
It's possible that your BIOS doesn't fully reset the NIC upon startup.
It's also possible there are issues with the ath9k power save/resume
code. It's also possible they're all compounding to make things worse.
Are you able to completely and utterly disable any/all power saving on
ath9k, including APSM if you have it enabled?
Unfortunately the information I have is a bit sketchy. I'll do some
further digging (and hope I don't bug Atheros people too much :) to
see if I can extract out some more information about what's going on.
Thanks,
Adrian

That's interesting. Could you give me a clue how to implement this?
Also after doing that, will it be enough to use only one physical
antenna connector?

It depends on how it's all wired up. And yes, once you know how it's
wired up and which antenna configuration words to program in, you can
run just one of three antennas.

Try using "1 1" instead of "all all".

Do not mess with the rx_chainmask/tx_chainmask parameters, that may be
the reason why it's not working for you.

That sounds like a good plan. When that is posted, I'll study if that kind of

And the last question...
Can you confirm that after setting antenna configuration to 1x1 I can
safely detach 2nd physical connector from the adapter? I mean is there
a guarantees that device will only use the 1st antenna.

If this change is made, it has to be tested on all supported devices, IMO.
I would not be surprised if there are older devices that don't like that.

Two of my devices are a BCM4303 (14e4:4301), and an early BCM4306. There are not
likely to be any older than that.

Changing the antenna configuration will alter the chainmask accordingly,
so it should be safe to disconnect the second physical connector.

In my case, with 3.1-rc9, an atheros SR71 card stopped apparently
negotiating N - as it would not connect faster than 54Mbit on the 5ghz
channel either in HT20 or HT40+ mode, according to sampling iwconfig.
